Ben Clayton c2c46a0533 test-runner: Consider wgsl output as validated
The resolver is the closest thing to a validator in this case.
Enables `--generate-expected` for WGSL files that were previously marked as SKIP.

David Neto 1e19b55d19 spirv-reader: switch to HLSL-style pipeline IO
- When storing to sample_mask output, write to the 0th element
- Only make a return struct if it has members
- Adjust type signedness coercion when loading special builtins.
- Adapt tests

- Update expectations for end-to-end tests

- Handle sample_mask with stride
  Input variables normally don't have layout. But they can have it
  up through SPIR-V 1.4.
  Handle this case in the SPIR-V reader, by seeing through the
  intermediate alias type created for the strided array type.

Ben Clayton cfed1cb01e ast: Tweak cloning rules for module-scope decls
Previously the Clone() of the AST would clone all the functions, globals
and type declarations in a temporary vector, then assign this to the
ast::Module. This meant that adding new module-scope declarations inside
callbacks of ReplaceAll() would place them right at the top, before any
of the cloned declarations.

As top-level declarations are not statements, ensuring that a new object
comes before the current ReplaceAll() declaration is surprisingly
tricky.

With this change, we can now safely assume that calling
ProgramBuilder::Var(), ProgramBuilder::Func(), ProgramBuilder::Alias()
or ProgramBuilder::Structure() inside a ReplaceAll() will add that
module-scoped declaration before the currently processed top-level
declaration.

James Price 0f1efe04c3 writer/msl: Fix texture intrinsic generation
Wrap the texture expression in parentheses when it has lower
precendence than the function call operator.

Cast integer coordinates to unsigned integers as required by MSL.

Emit [[texture()]] and [[sampler()]] attributes on these entry point
parameters.

James Price 2940c7002c writer/msl: Avoid generating unnecessary pointers
When moving private and workgroup variables into the entry point,
generate pointers to pass as arguments to sub-functions on demand,
instead of upfront. This removes a bunch of unnecessary dereferences
for accesses inside the entry point, and one function variable.
