18f3cd6810 GLSL: Ensure ray query object decls are flushed if allocated in Function. 
glslang always emits Private variables, but DXC not so much.

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.

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.

a11c4780d0 GLSL: Emit nonuniformEXT in correct place for late-combined samplers. 
Need to emit nonuniformEXT(sampler2D()) since constructor expressions in
Vulkan GLSL do not propgate the nonuniform qualifier.

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.

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.

bae76d7915 GLSL: Use for-loop fallback instead of do/while for legacy ESSL.

2.0 implementations.

0ebb88cc39 MSL: Redirect member indices when buffer has been sorted by Offset. 
If a buffer rewrites its Offsets, all member references to that struct
are invalidated, and must be redirected, do so in to_member_reference,
but there might be other places where this is needed. Fix as required.
SPIR-V code relying on this is somewhat questionable, but seems to be
in-spec.

5e5d1c27ce GLSL: Support f16x2 <-> f32 bitcast. 
There is no native formulation, so introduce a concept of a "complex"
bitcast to handle odd-ball cases which have no native unary operation.
