37d92ca244 tint/spirv: Fix atomicCompareExchangeWeak
We were missing an `UnwrapRef` when generating the return type, and
were generating invalid SPIR-V when the value being stored was a
reference. The auto-generated builtin tests only test with literal
values.

3ad927cc73 tint/writer: Check for inf / nan after casting to f32.
When abstract floats are supported, FloatLiteralExpression may hold values outside of the range of a f32. When we call FloatToString(), we may emit an 'inf', which is not a token for any backend.

Cast to f32 first, to ensure behavior remains consistent.

Note: Once the resolver materializes, and we constant fold, the backends shouldn't see any values outside of a f32.

55c0c9d950 tint: Add abstract numerics to vector and matrix constructors
These are the first intrinsics to support abstract-integers and
abstract-floats.

Nothing can use these yet, as the resolver hasn't had abstract numerics
enabled in production builds.

8f4f449540 tint/writer: Do not attempt to use invalid programs
Attempting to emit shader code from an invalid program is unsafe.

The WGSL writer is used for dumping information which is valuable for debugging bad programs, so this has not been changed.

6522837acb tint: Add enable_abstract_numerics flag on Resolver
When enabled, unsuffixed literals will be treated as abstract numerics.
By having this disabled by default, we can build up the tests without
the risk of breaking production code.

This flag is enabled for resolver unit tests. This can safely be done
with no change in tested behavior, as all tests use the '_i' or '_u'
literal suffixes, so currently there are no tests that exercise abstract
numerics.

ab4c035762 tint: fix HLSL countOneBits and reverseBits for i32 args
These two functions in HLSL only accept and return uint. Thus, if the
result of these calls is passed to a function that wants int, it will
fail, or call the uint overload if one exists. Fixed by casting the
result to int if the arg is int.

e5a67ac891 tint: Remove ast::CallExpression -> sem::Call implicit mapping
With abstract materialization, any ast::Expression may map to the new
sem::Materialize node. Because of this, we can't assume that an
ast::CallExpression maps to a sem::Call, as it might be wrapped by a
sem::Materialize.

Remove the mapping, and fix up all the code that was relying on this.

Fixes are done by either:
• Calling `UnwrapMaterialize()->As<sem::Call>()` on the semantic
  expression. This is done when the logic may assume it's possible for
  the expression to be a Materialize node.
• Using the explicit sem::Info::Get<sem::Call>() template argument to
  cast the semantic type to sem::Call. This is done when the logic
  either knows it is impossible for the expression to be a Materialize.

The backends have been stubbed, as we'll want to emit the constant value
for these nodes. It's likely that we'll just use the FoldConstants
transform to strip all Materialize nodes from the tree. For now, be
defensive.
