We can no longer rely on the `patch_control_point<>` array being
present, so the best we can do is use the value given us at compile
time.
This was an oversight on my part when I initially implemented the
raw-buffer tessellation evaluation input mode. The lack of tests for the
`PatchVertices` built-in almost certainly contributed, so I fixed that
in this patch.
Fixes the test
`dEQP-VK.tessellation.shader_input_output.patch_vertices_in_tes`. This
is the last failing test under `dEQP-VK.tessellation`.
By default, the matrix would be declared as mediump, causing precision
issues. Need to dispatch to two separate functions since GLSL does not
support overload based on precision.
Fixes the CTS test
`dEQP-VK.spirv_assembly.instruction.compute.opundef.undefined_constant_composite`
and helps with another,
`dEQP-VK.spirv_assembly.instruction.compute.opundef.undefined_spec_constant_composite`.
Unfortunately, fixing the latter requires another change.
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.
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.
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.

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.
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.
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.
