863d9edf59 GLSL: Change Add[Spirv]BlockAttribute to support GLSL
Modify the AddSpirvBlockAttribute transform to fix top-level structure
access of uniform, storage and push-constant buffers for use in the
GLSL backend. The small change to the transform makes the transform
wrap host-sharable buffers, if they're also used as a
non-host-sharable structure. Also rename the transform to
AddBlockAttrbibute in order to reflect its wider applicability.

8b30ca3efa tint/transform: Fix FoldTrivialSingleUseLet for abstracts
If the let initializer was an abstract numeric that was implicitly materialized to a concrete type, then we could inlining the initializer into the use without the implicit materialization cast.
This could lead to validation errors, and subtly different results in the program.

In this situation, add an explicit cast to keep the types the same before and after inlining.

648bd7b4be tint: Add TINT_REFLECT() & ForeachField()
This uses template and macro magic to reflect the fields of a class.

Dawn:
* Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn().

Fuzzers:
* Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system.
* static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing.

Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture.

All this reduces fragility of the struct declarations slipping out of sync with the uses.

VectorizeMatrixConversions, are also added for SPIRV to replace a matrix
conversion to a matrix construction with converted column vectors.

Debug and Release mode on OSX setting these flags caused piles

way to fix this, but it does fix the warnings. We need to decide
if we want to hide symbols by default and, if so, figure out how
to fix the downstream projects.

93c2d559a1 tint/utils: Default to using Hasher instead of std::hash
STL std::hash<T*> implementations have a tendency of just reinterpreting the
pointer as a size_t. This is fast, but produces a bad hash, as most pointers
tend to be 4 or 16 byte aligned. The lack of entropy in the LSBs causes
clustering of hashmap slots. Use tint::utils::Hasher to get better hashes.

a838e34954 Handle peeking past placeholder elements.
Currently when peeking, if there is placeholder then anything after
the `peek(0)` will be off by 1 position as the placeholder will
end up included in the index count.

This CL updates the peek routine to correctly skip over any
placeholder element between the current index and the requested
peek token.

158c85dab4 Add new relational rules to WGSL grammar.
This CL adds the `relational_expression.post.unary_expression` grammar
rule into the WGSL parser. A `shift_expression` helper and a
`relational_expression` helper are also added.

Note, the two helpers have `maybe_` as name prefixes. This will be
dropped when the old parser path is removed which current uses the
other versions of those names.
