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.

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

ae9ca7d73c MSL: Fix copy of arrays to/from stage IO variables. 
Need to take into account effective storage classes and whether or not
we target stage IO blocks since native arrays are conditionally enabled.

ee31e84e30 GLSL: Handle complex load/store scenarios to gl_SampleMask. 
Need special workarounds to handle array load/store since array size is
unsized in GLSL, and array copy is not possible.
Also, consider bitcast for scalar loads and stores.

7ab3f3f74e Deal better with CompositeExtract from constant composite. 
There is no good reason for applications to emit this kind of code, but
some do. Special case this scenario.

2097c30985 GLSL: Support both SPV_KHR_ray_tracing and NV_ray_tracing. 
Fairly minor differences, so can keep them side by side without too much
effort. NV support is effectively deprecated now however.

- Add OpConvertUToAccelerationStructureKHR
- Ignore/Terminate ray is now a terminator in KHR, but a call in NV.
- Fix some bugs with reportIntersection.

Need to emit nonuniformEXT(sampler2D()) since constructor expressions in
Vulkan GLSL do not propgate the nonuniform qualifier.

matrices via a wrapper function.

3e6010d8c5 MSL: Don't use a bitcast for tessellation levels in tesc shaders. 
`half` cannot be bitcasted to `float`, because the two types are not the
same size. Use an expanding cast instead.

We were already doing this for stores to the tessellation levels; why I
didn't also do this for loads is beyond me.

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.

57c93d44ac GLSL: Add option to force flattening IO blocks. 
It is not always desirable to use actual blocks.
A prime example in the case where EXT_shader_io_blocks is not supported
on the target implementation.

fa5b206d97 MSL: Workaround broken vector -> scalar access chain in MSL. 
On MSL, the compiler refuses to allow access chains into a normal vector type.
What happens in practice instead is a read-modify-write where a vector type is
loaded, modified and written back.

The workaround is to convert a vector into a pointer-to-scalar before
the access chain continues to add the scalar index.

3afbfdb090 Implement context-sensitive expression read tracking. 
When inside a loop, treat any read of outer expressions to happen
multiple times, forcing a temporary of said outer expressions.
This avoids the problem where we can end up relying on loop-invariant code motion to happen in the
compiler when converting optimized shaders.

03d4bcea68 MSL: Improve handling of array types in buffer objects. 
When loading and storing array types which belong to buffer objects, we
need to treat these values as not being value types. Also, need to
handle array load/store from/to more address space combinations.
