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.

Also fixed implementation of this atomic in GLSL. It was emitting code
that would not compile because, as for HLSL, we must pass in the
variable directly to atomic funcs, not via an in/out arg to a function.

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.

When converting values between two concrete types, handle the case that
the value is unrepresentable by the target type.
For integers, the converted value will be either the maximum or minimum
value for the integer type.
For floats, the converted value will be positive or negative infinity.

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.

Instead of vector-of-variant.
This:
• Makes it impossible to produce a mix of scalar variant types, which
would make no sense.
• Reduces the size of a Constant, by removing the union-tag from each
element.
Also clean up terminology. Rename 'Constant::Scalar' to
'Constant::Element'. Scalars are well-defined in WGSL, and with the
introduction of abstract-numerics, this no longer makes sense.

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.

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.

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.
