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.

Ben Clayton 9b54a2e53c Implement Pointers and References
This change implements pointers and references as described by the WGSL
specification change in https://github.com/gpuweb/gpuweb/pull/1569.

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

fail.  This lets us get extract a corpus of SPIR-V modules, and
lets us more easily verify that the test shaders are valid in the first
place.

Also:
- 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

This is useful for bulk testing

Remove all sem::Type references from the AST.
ConstructedTypes are now all AST types.

The parsers will still create semantic types, but these are now disjoint
and ignored.
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
up at the end of parsing. However, duplicates added as global
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.

Ben Clayton 109b18f504 ast: Remove types from ast::Literals
A literal has an implicit type, so there should be no type on the AST node.

This highlighted that the resolver was nto canonicalizing TypeConstructorExpression types, which has been fixed.
This required preservation of the declared type name in order for error messages to contain aliased names.

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

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.

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.

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.

There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

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.

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 42d1e097e6 Have ProgramBuilder::Func() register the function

Add helpers on Program and ProgramBuilder that significantly simplify

Also demangle - this also reduces a bunch of copy-pasta code.

Ben Clayton dd1b6fca9f Introduce semantic::Info
Will hold the mutable fields that currently reside in the otherwise immutable-AST.

Change the AST string methods to accept a `const semantic::Info&`. This is required as some nodes include type-resolved information in their output strings.
