9b2a8c7622 HLSL: Ensure synthetic NumWorkgroups variable is considered active. 
In SPIR-V 1.4+, active global variables must be marked as such.

d6b29ab017 HLSL: Rewrite how block IO is emitted. 
Emit block members directly in the IO structs and sort them.
Ensures we can get some kind of stable order between stages.

To complete the story, we'll need to be able to inject unused inputs /
builtins, or eliminate unused outputs (probably easiest solution).

8216e87f02 Handle SPIR-V 1.4 selection constructs. 
Fix bug in to_trivial_mix_op, where we made a pre-1.4 assumption that
component count of selector is equal to value component count.

e47a30e807 Honor NoContraction qualifier. 
We'll need to force a temporary and mark it as precise.
MSL is a little weird here, but we can piggyback on top of the invariant
float math option here to force fma() operations everywhere.

0e963c62b6 HLSL: Support Shuffle wave ops. 
WaveReadLaneAt is no longer restricted to dynamically uniform index,
so can implement the other shuffle ops.

532f65583e Rewrite how non-uniform qualifiers are handled. 
Remove all shenanigans with propagation, and only consume nonuniform
qualifiers exactly where needed (last minute).

6a614cc7f7 Normalize all internal workaround methods to use spv prefix. 
We have been interchanging spv and SPIRV_Cross_ for a while, which
causes weirdness since we don't explicitly ban SPIRV_Cross identifiers,
as these identifiers are generally used for interface variable
workarounds.

66afe8c499 Implement a simple evaluator of specialization constants. 
In some cases, we need to get a literal value from a spec constant op.
Mostly relevant when emitting buffers, so implement a 32-bit integer
scalar subset of the evaluator. Can be extended as needed to support
evaluating any specialization constant operation.

a07441568e Overhaul how we deal with reserved identifiers. 
- Do not silently drop reserved identifiers in the parser. This makes it
  possible to reflect identifiers which are reserved by the
  cross-compiler module.
- Instead of dropping the name, emit _RESERVED_IDENTIFIER_FIXUP in the
  source to make it clear that a name has been rewritten.
- Document what is reserved and not.
