Ben Clayton 224ce729cc resolver: Add more inferred access tests
The tests that were in ptr_ref_* should have been in var_let_*. Move these to the right place, and add more tests that actually test the pointer access.

Ben Clayton 03d10721e7 Stop tint.h from including program_builder.h
ProgramBuilder is about as internal as you can get - this really should not be public.

MSVC seems to try an instantiate some of the template methods in ProgramBuilder when it is included externally (for PCH or DLL exports perhaps?), and failing with bizzare error messages that contain no point-of-instantiation.

As this header was never intended to be public in the first place, detect and error if the tint.h include guard is found while processing program_builder.h, and fix up the couple of bad transitive includes.

Fixes tint -> dawn autoroller

Ben Clayton 93e8f527ee wgsl: Deprecate [[access]] decorations
Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.

The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
   var x : [[access(x)]] alias_to_struct;

Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.

Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.

Ben Clayton 620d77e480 PB: Make Var() and Global() params optional
and allow them in any order.

We're about to add Yet Another optional parameter - access control.
For style, we probably want this field before the decorations, however
that means adding more default values for all the cases where we don't
need to specify the access control.

Instead use some template magic to allow extra parameters to be
specified in any order, and entirely optional, with sensible defaults.
This keeps things readable and without huge code refactorings.

Subormal numbers are emitted as hex float.

Handling Inf and NaN is unresolved in the spec.

NaN tests are disabled, due to platform dependence.

Previous logic relied on the fact that for most operations, for a given
lhs type, there was exactly one rhs type allowed, except for
multiplication. This is no longer true in the spec, so making this test
work is more complex now. Instead, we simplify the test by having it
take the cartesian product of all possible (type * type * op), and
skipping any triplet not found in the all_valid_cases table.

James Price 70f80bb13d ast: Support non-literal workgroup_size parameters
Change the type of the values in an ast::WorkgroupDecoration to be
ast::Expression nodes, so that they can represent both
ast::ScalarExpression (literal) and ast::IdentifierExpression
(module-scope constant).

The Resolver processes these nodes to produce a uint32_t for the
default value on each dimension, and captures a reference to the
module-scope constant if it is overridable (which will soon be used by
the inspector and backends).

The WGSL parser now uses `primary_expression` to parse arguments to
workgroup_size.

Also added some WorkgroupSize() helpers to ProgramBuilder.

Antonio Maiorano 05743afb56 Revert "Add DuplicateStorageStruct transform"
This reverts commit 594075a2f0.

Reason for revert: This is not a complete solution. It does not cover assignment of variables of the same struct type, but of different access types. For example:

```
[[block]] struct S{ i : 32; };
var<storage> gr : [[access(read)]] S;
var<storage> gw : [[access(write)]] S;
fn f() {
  var a : S;
  a = gr;
  gw = a;
}
```

With my CL, we currently generate invalid assignments because the new types of 'S' for 'gr' and 'gw' are now all different types. We would need to generate functions to assign between them.

In the end, we will drop this strategy, and instead, Dawn will be modified to not rely on names.

Original change's description:
> Add DuplicateStorageStruct transform
>
> This transform is currently required by Dawn for it's GLSL backend so
> that SPIRV-Cross does not end up renaming the structures internally,
> which it does to fix aliasing problems. We can remove this transform
> if/once Dawn using binding numbers rather than names for uniform/storage
> buffer data.

reader/spirv:
* Now emits address-of `&expr` and indirection `*expr` operators as

* As an identifier may now resolve to a pointer or reference type
  depending on whether the declaration is a `var`, `let` or
  parameter, `Function::identifier_values_` has been changed from
  an ID set to an ID -> Type* map.

resolver:
* Now correctly resolves all expressions to either a value type,
  reference type or pointer type.
* Validates pointer / reference rules on assignment, `var` and `let`
  construction, and usage.
* Handles the address-of and indirection operators.
* No longer does any implicit loads of pointer types.
* Storage class validation is still TODO (crbug.com/tint/809)

writer/spirv:
* Correctly handles variables and expressions of pointer and
  reference types, emitting OpLoads where necessary.

test:
* Lots of new test cases

sem::BlockStatement class.

In the process, semantic information about statements in general is
overhauled so that a statement has a reference to its parent
statement, regardless of whether this is a block.

Antonio Maiorano dc4e6c1844 Remove sem::AccessControl
In preparation for implementing
https://github.com/gpuweb/gpuweb/issues/1604, this change removes the
sem::AccessControl node. Instead, the ast::AccessControl::Access enum is
now on the sem::StorageTexture class, as well as on sem::Variable. For
sem::Variable, the field is set when the variable's type is either a
storage buffer or a storage texture.

Add a new parameter to BindingRemapper::Remappings that allows resulting binding points to collide.

When enabled, the output of the transform contains two or more module-scoped variables with the same binding point, used by the same entry point, then these variables will be decorated with an internal decoration to disable validation for the collision.

This is to work around collisions generated for the HLSL backend where the variables actually exist in different register classes, which is permitted by D3D12.

The transform will only generate these decorations if it needs to.

These originate from a time before Castable, and there were hand-written Is<T>() methods on each of the base types.

Castable has its own tests that ensure the Is<T>() and As<T>() work as expected.
We don't need to check that this logic works for every type that derives from castable.

Ben Clayton fcda15ef67 Move storage_class validation from wgsl to resolver
We don't want the WGSL parser to have to maintain type lookups.
If the WGSL language is updated to allow module-scope variables to be declared in any order, then the single-pass approach is going to fail horribly.

Instead do the check in the Resovler.
With this change, the AST nodes actually contain the correctly declared storage class.

Fix up the SPIR-V reader to generate StorageClass::kNone for handle types.
Fix all tests.

lets us more easily verify that the test shaders are valid in the first

- Add test/extract-spvasm.py to split that output to separate SPIR-V
  assembly files
- Add optional second argument test/test-all.sh to specify a directory
  look for input files.
- BUILD.gn:  Add dependency from //test:tint_unittests_main to
  //test:tint_unittests_config to pick up source dependency on
  the internal header of the SPIRV-Tools optimizer, needed by
  the indirection through src/reader/spirv/parser_impl_test_helper.h

ConstructedTypes are now all AST types.

The parsers will still create semantic types, but these are now disjoint

The parsers will be updated with future changes to stop creating these
semantic types.

Resolver creates semantic types from the AST types. Most downstream
logic continues to use the semantic types, however transforms will now
need to rebuild AST type information instead of reassigning semantic
information, as semantic nodes are fully rebuilt by the Resolver.

My last CL (https://dawn-review.googlesource.com/c/tint/+/49542) made it
so that AST nodes are re-created every type we resolve a spirv type id
to a tint type. This creates duplicate nodes, most of which are cleaned

constructed types are not handled, so this CL makes sure we do not add
said duplicates.

Antonio Maiorano 1b898d56b4 spirv parser: create ast types along with sem types
The spirv parser now creates ast types along with sem types via
typ::Type. All sem::Type* were replaced with typ::Type, and its `ast`
member is used over the `sem` member to make it easier to migrate to
ast-only.

The parser was written to take advantage of the fact that types were
resolved to semantic types during parsing. For instance, a mapping of
spirv typeid to sem::Type* was used throughout (`id_to_type_`) to
resolve types once, and to support type aliasing. Since the goal is to
only create AST types, and to resolve only in the Resolver, I made many
changes to remove this dependency on semantic types. For instance, we
now always call ConvertType(typeid) instead of looking up via
id_to_type. Similarly, the `signed_type_for_` and `unsigned_type_for_`
maps were replaced with `UnsignedTypeFor` and `SignedTypeFor` functions.

James Price 5f7f7c0f9e Revert "transform/EmitVertexPointSize: Handle entry point parameters"
This reverts commit e6307e5100.

Reason for revert: This change assumes that vertex shaders do not return void, but the validation for this is currently disabled since CTS still has vertex shaders that return void.

Original change's description:
> transform/EmitVertexPointSize: Handle entry point parameters
>
> Generate a new struct that contains members of the original return
> type with the point size appended to it, and replace return statements
> as necessary.
>
> The SPIR-V sanitizer then special-cases this builtin when handling

David Neto d30047fea0 spirv-reader: always reserve entry point names
We have to be careful when the same function is used for
two entry points.  The first entry point name will be registered
as the name for the function ID.  But subsequent entry points
should have their names reserved in the namer, even if they
aren't associated with an ID.

Antonio Maiorano 73fdc16c33 wgsl parser: replace almost all sem::Type* with typ::Type where possible
All that remains in the wgsl parser that references sem::Type* are
the register_constructed funcs/types, and adding an ast::ExternalTexture
type.

Also:

* Added specialization of OperatorArrow for type::TypePairs that returns
the value by reference so that operator-> can chain properly.

* In a few places where we expect the type to implicitly cast to a
pointer for a bool expression, e.g. `if (type)` or `TINT_ASSERT(type)`,
I added access to the `.sem` member of the TypePair. I tried adding an
implicit cast to bool, but this results in ambiguity in gtest for
equality comparisons.

* Constified more type pointers in type nodes

* Replaced header includes with forward declares in wgsl/parser_impl.h

also brings us one step closer to constifying types everywhere.

Ben Clayton 440636c15c Add typepair.h
Introduces typ::Type which wraps a templated pair of AST and SEM type pointers.
This is a temporary helper to ease migration of the thousands of tests that use the ProgramBuilder over from sem::Type to the new ast::Types.

Corentin Wallez c0810e7e6e Fix gn check in Chromium
- Move headers from libtint_sem_src into libtint_core_all_src so that
there is no circular header dependency between headers of these two
targets. libtint_sem_src is now just a hack to have a different name for
a few .cc files.
 - Made libtint_core_src publicly depend on its deps so that headers of
libtint_core_all_src are made visible through it.
 - Added spvtools dependencies in a couple places that were mistakenly
removed in a previous commit.
 - Moved helpers common to multiple unittest targets out of
tint_unittests_core_src and into a tint_test_helpers target that
all tint_unittests_source_set depend on.
 - Ran GN format that reordered some lists a bit.

Ben Clayton 6fcefe4c25 Resolver: Check that every AST node is reached once
AST nodes must not be shared. Diamonds in the AST will cause all sorts
of exciting, non trivial bugs.

All AST nodes must be reached by the Resolver. There are two common
reasons why they may not be:
(a) They were constructed and not attached to the AST. Several
    transforms scan the full list of constructed AST nodes to find nodes
    of a given type. Having detached nodes will likely cause bugs in
    these transforms. Detached nodes is also just a waste of memory.
(b) They are attached to the AST, but the resolver did not traverse
    them. Having the resolver skip over parts of the AST will fail to
    catch validation issues, and will leave semantic gaps, likely
    breaking downstream logic.

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

Ben Clayton 0ecea57a8a Add ShareableCloneable, dervies from Cloneable
The CloneContext will currently de-duplicate any pointers that are cloned multiple times, however this isn't ideal behavior for AST nodes.

AST nodes must be unique in the tree, so a non-transform clone of the AST from one program to another should only ever Clone() called once per node. Hitting the map for these is inefficent, worse still, there are cases in the transforms where we actually *want* to create N copies of the same source node. The current implementation makes this impossible.

This change introduces ShareableCloneable, a new base class that derives from Cloneable.
Repeated calls to CloneContext::Clone() for Cloneable pointer types will now produce a new, unique instance per call.

Repeated calls to CloneContext::Clone() for ShareableCloneable pointer types will de-duplicate as before.

type::Type objects are shared, want deduplication while cloning, so now derive from ShareableCloneable.
ast::Node continues to derive from Cloneable.

Ben Clayton 26cd48603d Castable: Add FLAGS template argument for Is,As
[Is,As] contain a static_assert() that checks a cast is actually possible (TO -> FROM share a common base class).
This has been extremely valuable - it's caught numerious impossible casts due to stupid mistakes - however it makes certain generic templates impossible to write.

Add a compile-time FLAGS argument to Is() and As(), which accepts a new kDontErrorOnImpossibleCast flag.
When specified, this static_assert will always pass, allowing impossible casts to be attempted.

Almost all transforms should clone all symbols before doing any work,
to avoid any newly created symbols clashing with existing symbols the
source program and causing them to be renamed.

The Renamer is the exception to this, and so an optional flag is used
to prevent automatic cloning of symbols for this transform.

The MSL validation logic itself is conditionally compiled based on the
TINT_BUILD_MSL_WRITER define. The TINT_BUILD_* flags were previously

the common/public tint configs when building the tint_unittests_main

Ben Clayton 363a2e26e3 SymbolTable: Change behavior of anonymous symbols
SymbolTable::New() used to build and return a symbol without a registered name. When you asked for the name of the symbol it would return tint_symbol_N, where N is the numerical identifier for the symbol.

This approach was a major tripping hazzard for  transforms that liked to fetch the source program name, and register it in the new program (in this situation, you should always use `CloneContext::Clone(Symbol)`).
Without special casing for unnamed symbols, you could end up promoting the unnamed symbol to a named symbol, and then colliding against a new unnamed symbol.
This is exactly what happened in tint:711.

Instead, with this change:

* The concept of unnamed symbols has been removed. All symbols  now have a name.
* The signature of `SymbolTable::New()` has been changed to take a name parameter (which defaults to 'tint_symbol'). This can be used to create a new, unique named symbol (possibly with a suffix), which will not collide with any existing symbols. Note these symbols may still collide if `SymbolTable::Register()` is called with the same name. All Transforms that currently use `SymbolTable::Register()` will be fixed in another change.
* The CloneContext has been updated to use `SymbolTable::New()` instead of `Register()`. This means that any symbols defined before a clone will not collide.
* `CloneContext::CloneSymbols()` has been added which allows a transform to pre-clone all the symbols from the source program. This can be used to avoid the authored identifiers being suffixed with a number, in the case a transform calls New() before the symbol is cloned.
* `Symbol::to_str()` has been changed to return `$<id>` instead of `tint_symbol_N`. This is to avoid any confusion between the actual name and the symbol ID.

David Neto 0386472762 spirv-reader: fix overly aggressive dominance check
When finding the true-head, false-head, and potentially the
premerge-head blocks of an if-selection, there was an overly
aggressive check for the true-branch or false-branch landing
on a merge block interior to the if-selection. The check was
determining if the merge block actually corresponded to the selection
header in question.  If not, then it was throwing an error.

The bug was that this check must be performed only if the
target in question is actually inside the selection body.
There are cases where the target could represent a structured
exit, e.g. to an enclosing loop's merge or continue, or
an enclosing switch construct's merge.

There is still a latent bug: if either the true branch
or false branch represent such a kLoopBreak, kLoopContinue, or
kSwitchBreak edge, then those are not properly generated.
That will be fixed in a followup CL.

Antonio Maiorano 2543686412 Resolver: compute canonical types and store them as semantic::Variable::Type
We define the canonical type as a type stripped of all aliases. For
example, Canonical(alias<alias<vec3<alias<f32>>>>) is vec3<f32>. This
change adds Resolver::Canonical(Type*) which caches and returns the
resulting canonical type. We use this throughout the Resolver instead of
UnwrapAliasIfNeeded(), and we store the result in semantic::Variable,
returned from it's Type() member function.

Also:

* Wrote unit tests for Resolver::Canonical()

* Added semantic::Variable::DeclaredType() as a convenience to
retrieve the AST variable's type.

* Updated post-resolve code (transforms) to make use of Type and
DeclaredType appropriately, removing unnecessary calls to
UnwrapAliasIfNeeded.

* Added IntrinsicTableTest.MatchWithNestedAliasUnwrapping to ensure we
don't need to pass canonical parameter types for instrinsic table
lookups.

* ProgramBuilder: added vecN and matMxN overloads that take a Type* arg
to create them with alias types.

Ben Clayton 1b8d9f227b CloneContext: Don't create named symbols from unnamed
Registering a new Symbol with the NameFor() of the source symbol creates
a new *named* symbol. When mixing these with unnamed symbols we can have
collisions.

Update CloneContext::Clone(Symbol) to properly clone unnamed symbols.

Update (most) the transforms to ctx.Clone() the symbols instead of
registering the names directly.

Fix up the tests where the symbol IDs have changed.

Note: We can still have symbol collisions if a program is authored with
identifiers like 'tint_symbol_3'. This will be fixed up in a later
change.

- Non-struct entry point return type must have a pipeline IO attribute
- Structs used as entry point parameters and return values much have
  pipeline IO attributes on every member
- Structs used as entry point parameters and return values cannot have
  runtime array or nested struct members
- Multiple pipeline IO attributes on a parameter, return type, or
  struct member is not allowed
- Any given builtin and location attribute can only appear once for
  the return type, and across all parameters

Removed tests for nested structs from the SPIR-V transform/backend.

Fixed a couple of other tests with missing pipeline IO attributes.

Antonio Maiorano 9ef17472e8 Add semantic::Variable::Type() and use it instead of ast::Variable::type()
In anticipation of adding support for type inference, no longer use
ast::Variable::type() everywhere, as it will eventually return nullptr
for type-inferred variables. Instead, the Resolver now stores the final
resolved type into the semantic::Variable, and nearly all code now makes
use of that.

ast::Variable::type() has been renamed to ast::Variable::declared_type()
to help make its usage clear, and to distinguish it from
semantic::Variable::Type().

Fixed tests that failed after this change because variables were missing
VariableDeclStatements, so there was no path to the variables during
resolving, and thus no semantic info generated for them.

Corentin Wallez 399b88845c Quickfix for unknown warning in Chromium
Chromium uses clang 13.0 that likely removes the warning while Skia uses
clang 12.0 that still has the warning. Temporarily skip the
-Wno-return-std-move-in-c++11 in Chromium only while Skia changes to not
add warnings to it's third_party dependencies.

The Metal programming language is a C++14-based Specification with

Tint is written in C++14.

Take advantage of the fact that MSL is based on the same language that
Tint is written in, and validate that the field members match what the

Ben Clayton 5907039597 msl: Implement more types for structure layout
Implement layout logic for vectors, matrices and default-stride arrays.

Custom stride arrays are complex, and will be tackled as a followup change.

This change also emits byte offsets for all structure members as comments. This is even emitted for non-storage uses, which can be cleaned up as a followup.

Fixes a whole lot of TINT_ICE() for non-complex WGSL shaders.

well (these tests either passed the incorrect number of arguments to a
vector constructor or relied on implicit conversions between numeric

James Price 95d4077648 Flatten ast::Decoration class hierarchy
Remove the decoration groupings (Array, Function, Struct,
StructMember, Type, Variable), such that all *Decoration classes now
subclass ast::Decoration directly. This allows for decorations to be
used in multiple places; for example, builtin decorations are now
valid for both variables and struct members.

Checking that decoration lists only contain decorations that are valid
for the node that they are attached to is now done inside the
validator.

Ben Clayton 8454d824d4 ast: Replace IsValid() with TINT_ASSERT()
The readers must not produce invalid ASTs.
If readers cannot produce a valid AST, then they should error instead.
If a reader does produce an invalid AST, this change catches this bad behavior early, significantly helping identify the root of the broken logic.

IsValid() made a bit more sense in the days where the AST was mutable, and was constructed by calling setters on the nodes to build up the tree.
In order to detect bad ASTs, IsValid() would have to perform an entire AST traversal and give a yes / no answer for the entire tree. Not only was this slow, an answer of 'no' didn't tell you *where* the AST was invalid, resulting in a lot of manual debugging.
Now that the AST is fully immutable, all child nodes need to be built before their parents. The AST node constructors now become a perfect place to perform pointer sanity checking.

The argument for attempting to catch and handle invalid ASTs is not a compelling one.
Invalid ASTs are invalid compiler behavior, not something that should ever happen with a correctly functioning compiler.
If this were to happen in production, the user would be utterly clueless to _why_ the program is invalid, or _how_ to fix it.
Attempting to handle invalid ASTs is just masking a much larger problem.

Let's just let the fuzzers do their job to catch any of these cases early.

We now keep track of scopes as a tree of BlockInfos that track variables
declared in each scope. For loop scopes, we store the index of the first
variable (if any) that follows the first continue statement. Using this
data structure, when parsing expressions, we validate that used
variables in continuing blocks are not bypassed by a continue statement
in the parent loop block.

Also:
* Validate that continue statements are in a loop in TD. This error is
already caught by the spir-v writer, but better to catch it here.
* Add more utility functions to ProgramBuilder to make it easier to
write tests

The chromium tests for static initializers get upset about the call to
ClassId::New() in a global variable initializer.

Instead, take the address of a unique 'token' variable to generate the
unique identifier.

This is similar to how things were before
https://dawn-review.googlesource.com/c/tint/+/42460
but of taking the address-of the token in the header, we're instead
taking the address-of inside the cpp file, avoiding the DLL issues
that 42460 addressed.

function calls itself. Prior to this we'd find the called function and,
if the function was an entry point, end up in a loop trying to walk all
the callers. With this change, the function is not found when we do

Ben Clayton eb496d0a4d transform: API cleanup
Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.

Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.

Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Ben Clayton 33a8cddb2d TypeDeterminer: Error if an IdentifierExpression to a callable is not called
IdentifierExpressions that resolve to functions and intrinsics were not being assigned a semantic::Expression as there is no function / intrinsic type to give them. This lead to NPEs in the writers when these identifiers were reached and TypeOf() is called.

Adding a new tint::type::Callable is an option, but until functions become a type in the language, this seems like a very large and debatable change.

Attempting to detect IdentifierExpressions with no semantic node in the validator is another option, but this is clunky as it has to detect incomplete semantic info from the TD, and cannot identify whether this actually resolved to a function or an intrinsic.

Instead we now error in the TD if encounter an IdentifierExpression that resolves to a function or intrinsic which is not called (ident is not followed with parenthesis).

Ben Clayton 767df5f03b Fix infinite spin in wgsl parser
If the parser hits a `maximum parser recursive depth reached` situation, then we need to try and resynchronize the parser.

If we fail to do this, then the synchronized_ flag may remain true, and the parser will believe progress is still being made.
In this situation the parser may try to reparse the same token, forever.

By calling sync_to() we either find the end of the block, and forward progress can be made, or synchronized_ is set to false, and the parser can error out cleanly.

Add test case from fuzzer report.

There is a danger with Replace() or ReplaceAll(), where you can end up replacing a node with another node of an incompatible type for some reference of that object. Previously this would silently cast to the incorrect type, and Bad Things would happen. Now we will assert in this situation.

I have not observed this issue happening (all current uses of Replace() and ReplaceAll() are believed to be safe). This is just an edge case I've spotted and wanted to add some safety belts for.

James Price dfd1714174 [wgsl-writer] Emit globals in declared order
Instead of emitting all global variables and then functions, emit
global declarations in the order they were added to the AST.

This fixes issues where the reording might generate an invalid WGSL
program from a valid input (e.g. when declaring a global variable with
the same name as a variable inside a function that precedes it).

This also unifies the implementation of Generate() and
GenerateEntryPoint(), to avoid implementing the same logic twice.

This fixes false-positive "redeclared identifier" errors when a global

Ben Clayton 7b7d69854d TypeResolver: Fix TypeOf() for CallExpression
While traversing and resolving the AST, TypeOf() was called to look up
the semantic node for the given AST expression in order to fetch the
resolved type. However, for CallExpression semantic nodes are
constructed at the end of the AST traversal, and GetType() for these
would unexpectedly return nullptr, causing a crash.

To fix, have TypeDeterminer maintain an internal map of ast::Expression
to resolved type. Always populate this internal map whenever SetType() is
called. At the end of the AST traversal, have CreateSemanticNodes()
construct the semantic nodes for any ast::Expression nodes that do not
already have a semantic node assigned.

With this, GetType() will always return the type set with SetType().

Fixes tint -> dawn autoroller.

Ben Clayton 59d24735d0 Add IntrinsicTable
Provides a centeralized table for all intrinsic overloads.

IntrinsicTable::Lookup() takes the intrinsic type and list of arguments, returning either the matched overload, or a sensible error message.

The validator has expectations that the TypeDeterminer resolves the return type of an intrinsic call, even when the signature doesn't match. To handle this, create semantic::Intrinsic nodes even when the overload fails to match. A significant portion of the Validator's logic for handling intrinsics can be removed (future change).

There are a number of benefits to migrating the TypeDeterminer and Validator over to the IntrinsicTable:
* There's far less intrininsic-bespoke code to maintain (no more duplicate `kIntrinsicData` tables in TypeDeterminer and Validator).
* Adding or adjusting an intrinsic overload involves adding or adjusting a single Register() line.
* Error messages give helpful suggestions for related overloads when given incorrect arguments.
* Error messages are consistent for all intrinsics.
* Error messages are far more understandable than those produced by the TypeDeterminer.
* Further improvements on the error messages produced by the IntrinsicTable will benefit _all_ the intrinsics and their overloads.
* The IntrinsicTable generates correct parameter information, including whether parameters are pointers or not.
* The IntrinsicTable will help with implementing autocomplete for a language server

The reason we need the sem_ prefix is because all the tint lib code is compiled as a single target, and .GN cannot cope with .cc files with the same file name, even if they're in different directories.
This could be fixed by building each directory as a separate target, but we have circular dependencies that currently make this impossible.

Pull the mutable semantic field from ast::Identifier and into a new semantic nodes.
Have the TypeDeterminer create these new semantic nodes.

Note: This change also fixes the node that holds the semantic information for a call.
Previously this was on the identifier, and this is now correctly on the CallExpression.
The identifier of the CallExpression should resolve to the target function, not the return type.
Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.

Ben Clayton 401b96b9bb Simplify usage of the TypeDeterminer in tests
Make private all TypeDeterminer::DetermineXXX() methods, forcing all tests to use the root-level TypeDeterminer::Determine() method.
Remove TypeDeterminer::RegisterVariableForTesting().

The main use for calling the TypeDeterminer::DetermineXXX() methods was to perform type determination on a partial AST.
This was messy and often resulting in multiple calls into TypeDeterminer. Most tests already perform a full TypeDeterminer::Determine() call when the program is built, so many of these were redundant.
The exposure of these internal methods for testing also makes refactoring the TypeDeterminer extremely difficult.

Add a number of ProgramBuilder helper methods for attaching the partial AST in these tests to the root of the AST, greatly simplifying the use of the TypeDeterminer:
* ProgramBuilder::Global() and ProgramBuilder::GlobalConst() are helpers that register the variable returned by ProgramBuilder::Var() and ProgramBuilder::Const(), respectively.
* ProgramBuilder::WrapInFunction() is a variadic function that accepts variables, expressions and statements, attaching these to the root of the AST via a dummy function.

Most test classes now no longer use their own TypeDeterminer, and instead properly depend on the automatic type determination performed at Program build time.

Use ProgramBuilder::Wrap() in the writers, where we were previously

This is now required as semantic information is generated inside the
writers for newly constructed AST nodes, and we need to register
this semantic info so it can be fetched later.

Ben Clayton a6b9a8eb2f Split Program into Program and ProgramBuilder
Program is now immutable*, and remains part of the public Tint
interface.

ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.

Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().

Mutable ProgramBuilders can be moved into immutable Programs.

* - mostly immutable. It still has a move constructor and move
  assignment operator - required for practical usage - and the
  semantic information on AST nodes is still mutable.
