0e963c62b6 HLSL: Support Shuffle wave ops. 
WaveReadLaneAt is no longer restricted to dynamically uniform index,
so can implement the other shuffle ops.

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

ea02a0c03a Check entry point variables in is_hidden_variables.

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

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.

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.

dd1f53ff15 HLSL: Fix bug in is_packing_standard for cbuffer. 
Was not keeping offset in sync with actual_offset and HLSL could trigger
spurious realignments due to the straddle check.

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.

f79c1e2fed Deal with illegal names in types as well. 
- Fixes issue with clip_distance flattening in MSL where member to
  flatten from would come from to_member_name, where it should have used
  the builtin name directly. This member name was modified by this patch
  and broke clip distance test shaders.

- Some cleanups with ir.meta, use ir.find_meta instead to not create
  unnecessary hashmap nodes.

3b5c4c7316 Implement constant empty struct correctly on all backends.

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.

a0c13e4ee8 Do not consider aliased struct types if the master is not a block. 
It is possible for a shader to declare two plain struct types which
simply share the same OpName without there being an implicit
value/buffer alias relationship.

For to_member_name(), make sure to use the type alias master when
resolving member names. The member name may be different in a type alias
master if the SPIR-V is being intentionally difficult.

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.

c7eda1bce9 Test glsl.std450 more exhaustively.

cases.

Not all opcodes are covered here, just the arithmetic ones. FP64 packing
is also ignored.

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.

8b236f24f1 Fix infinite loop when OpAtomic* temporaries are used in other blocks. 
We made the mistake of registering a dependency on the atomic variable
even if the atomic result was forced to a temporary. There is no need to
register reads from atomic variables like this as we always force atomic
results to a temporary and argument read/writes do not need to be
tracked.

eeb3f24991 Properly deal with sign-dependent GLSL opcodes. 
The GLSLstd450 spec is very lax about input signs, so we need to do the
bitcasting dance to implement it correctly.

df3e21a762 Parser: Fix OpCompositeConstruct with OpUndef. 
Just treat any undefined argument as 0. It is risky to use the undefined
variable as it might not lower to a true constant.

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.
