Ben Clayton 8c9cc86076 tint/resolver: Simplify / optimize Validator::Call()
The resolver has sensible places to dispatch to ArrayConstructor() and
StructureConstructor(), so don't do additional, unnecessary type
dispatches.

Ben Clayton 6fb5d379c2 tint/sem: Add const to StructMember 'type'.
This should be immutable once the sem tree is built.
Add a hacky const_cast in Resolver for now, as this is preferable to
having some things non-const in sem.

Ben Clayton 5716611bf0 tint/resolver: Materialize objects when indexed with non-const index
If an abstract-vector or abstract-matrix is indexed with a non-constant index expression, then the resulting value is non-constant, and so cannot be abstract.

In this situation the materialization cannot be done post-index, so materialization must happen on the object before indexing.

Ben Clayton d5f53ab580 tint/resolver: Optimize constant evaluation methods
Materialize() was re-evaluating the constant values for the incoming
semantic expression, despite this already being evaluated. Just use the
sem::Expression::ConstantValue().

resolver.cc already has all the semantic pointers, so pass them in
instead of pointlessly hitting the ast -> sem map.

dan sinclair 3a2a279714 Fixup various warnings in Tint which were accidentally suppressed.
When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.

A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.

This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.

Ben Clayton 2a8861d20e tint: Rework errors around variable declarations
Standarize the messages, using 'let', 'override' or 'var'.

Module-scope 'let' needs to be replaced with 'const', but baby steps.

subnormal cases.
3. Implement and fix related unitests for f16 and f32.

Ben Clayton 33fe68ee0f tint/resolver: Prevent ICE with invalid input
Attempting to return an abstract-numeric when the function had no return type would trigger an ICE, as an abstract numeric cannot materialize to a void type.

Ben Clayton 451eee0fed tint: Stub intrinsic @const evaluation
Add support for @const to builtins in intrinsics.def.
Propagate this flag through to the intrinsic table.
Handle builtins that are @const annotated in the resolver.

Currently no intrinsics are decorated with @const, so there's nothing to
test (yet).

These are tests for when there's no explicit target type for a
materialization. In this case we expect an abstract-int to
materialize to an i32 and an abstract-float to materialize to a
f32.

Fix a bug uncovered where we were creating a transposed matrix.
