The --dump-spirv option tells tint_unittests to output the
SPIR-V assembly text for a module which did not make the SPIR-V reader
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

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

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

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.

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.

Once we start migrating over to just creating `ast::Type`s instead of a

be nullptr. Only create composite AST / SEM types if the inner type has
a non-nullptr AST / SEM 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

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

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.

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.

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.

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.

Inserting into *all* vectors that happen to contain the reference object is likely unintended, and is a foot-gun waiting to go off.

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.
