4ab5bbb4e5 Fixup names of anonymous inner structs.
Just like we try to fixup struct names for block types, inner structs
can be "anonymous" structs. HLSL codegen from DXC tends to emit this,
and emitting dummy struct names tends to break GL linkage on some
drivers.

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.

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.

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

Tests that the builtin is considered active.

ddb3c65648 Handle reserved identifiers for functions.
gl_ identifiers are already handled by fixups, so remove redundant code.

fdbc80d131 HLSL: Fix FragCoord.w.
Need to invert it, SM 4.0+ uses W, not 1/W (like Vulkan/GL).

fad36a6b28 HLSL: Deal with partially filled 16-byte word in cbuffers.
The last element of an array or matrix in HLSL cbuffers are not filled
completely, but only have a size equal to the base vector.

b8905bbd95 Add support for forcefully zero-initialized variables.
Useful to better support certain platforms which require all variables
to be initialized to something.

MSL actually supports empty structs, so enable that path as well.

b960ae3b70 HLSL: Partially implement Unordered compare.
We cannot correctly implement unordered equal/ordered not equal without
a lot of extra instructions which slows normal code down.

cf1bf1c6ae Update external/ to SPIR-V 1.5
Rolled the hashes used for glslang, SPIRV-Tools, and SPIRV-Headers to
HEAD, which includes the update to 1.5.

Added passing '--amb' to glslang, so I didn't have to explicitly set
bindings in a large number of test shaders that currently don't, and
now glslang considers them invalid.

Marked all shaders that no longer pass spirv-val as .invalid.

c365cc1b43 Deal with OpPhi and case fallthrough.
This is quite complex since we cannot flush Phi inside the case labels,
we have to do it outside by emitting a lot of manual branches ourselves.

This should be extremely rare, but we need to handle this case.

8eb33c8017 Support -1 index in OpVectorShuffle.
-1 (0xffffffff) literal means the component should be undefined.
Since we cannot express undefined directly, just use a 0 literal in the
appropriate type.
