4c345166dc GLSL: Implement task shaders.
Due to bugged glslang / spirv-tools w.r.t. terminator instructions,
add a hack to ignore invalid SPIR-V for the time being.

Promote Unreachable cases into break to avoid fallthrough.

d08ce828f4 Promote Unreachable cases into break to avoid fallthrough.
HLSL is very fussy about fallthrough in switch blocks, so promote
Unreachable blocks to breaks if they are inside a switch construct.

Some false positives are possible in weird multi-break scenarios, but
this is benign.

23662668dd Attempt more optimal codegen for OpCompositeInsert.
Speculate that we can modify the SSA value in-place. As long as it is
not used after the modify, this is fine.

Also need to make sure we don't attempt to RMW something that is
impossible to modify.

92164d38d1 GLSL: Do not analyze precision for Undef variables.
Undefs won't have a chance to emit aliases, and any expression depending
on Undef will be garbage either way.

7a6c2da9aa GLSL: Handle more proper semantics for RelaxedPrecision.
GLSL and RelaxedPrecision are quite different in what they affect.
RelaxedPrecision affects operations, while this is merely implied in
GLSL based on inputs.

This leads to situations where we have to promote mediump inputs to
highp, and the simplest approach is to force highp temporaries for
inputs which are consumed in a highp context. For completeness, we also
demote RelaxedPrecision inputs to mediump variables.

PHI is handled by copying the PHI into a temporary.

We have to be very careful with hoisted temporaries, since the child
temporary will not be analyzed up-front. We inherit the hoisted-ness
state and emit the hoisted child temporary as necessary. When faking the
temporaries with OpCopyObject, we make sure to block any variable
hoisting.

Hoisting children of PHI variables is fine, since PHIs are not hoisted with
the same framework as other temporaries.

31be74a853 Add relax_nan_checks options.
Makes codegen from typical D3D emulation SPIR-V more readable.
Also makes cross compilation with NotEqual more sensible.
It's very rare to actually need the strict NaN-checks in practice.

Also, glslang now emits UnordNotEqual by default it seems, so give up
trying to assume OrdNotEqual. Harmonize for UnordNotEqual as the sane
default.

905b8244e7 Clamp vector element access to vector size.
In cases where we know the size of the vector and the index at compile
time, we can check if it's accessing in bounds and rely in undefined
behavior otherwise.

f1b411c9e8 GLSL: Deal with buffer_reference_align.
This is somewhat awkward to support, but the best effort we can do here
is to analyze various Load/Store opcodes and deduce the ideal overall
alignment based on this. This is not a 100% perfect solution, but should
be correct for any reasonable use case.

Also fix various nitpicks with BDA support while I'm at it.

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.

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.

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.
