7b9eaf0b5e MSL: Handle awkward mix and match of Offset / ArrayStride in constants. 
In normal buffer blocks, every member must be declared, but for
constants, you can technically mix and match, causing much pain and
suffering ...

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.

1ec9d018fd MSL: Handle aliased variable names for resources placed in IB struct. 
Just remember to register the names.

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.

9b25581d49 MSL: Handle constant construct of block-like array types. 
Need this to be context sensitive, since array of block-like struct is
template, but struct of block-like array is C-style.

Also, test a mix and match, so we have constant array of block-like
struct with array inside. :v

5a5be7f9b9 MSL: Handle signed atomic min/max. 
C++ deduces this based on the pointer type, so cast to atomic_uint/int
if we have to.

7c83fc22fa Add support for LocalSizeId. 
WorkgroupSize builtin is deprecated in 1.6 and LocalSizeId is supported
in Vulkan starting with maintenance4.

6071df5840 Fix wrong detection of trivial_mix_op. 
Effectively, only the last component of the select was considered, need
to correctly early out if any case is hit.

f72bb3c6f5 Improve handling of INT_MIN/INT64_MIN literals. 
We cannot naively convert these to decimal literals. C/C++ (and thus
MSL) has extremely awkward literal promotion rules.

2eea6a579b MSL: Consider that function/private variables can be block-like. 
Handles a special case with array copies.
The implementation of this fix is not perfect, but should be good
enough for time being.

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.

We need to handle loads from array as well, so the float4 hack doesn't
work.

look at member decorations.

23da445bd4 MSL: Emit multiple threadgroup slices for multi-patch. 
Multiple patches can run in the same workgroup when using multi-patch
mode, so we need to allocate enough storage to avoid false sharing.

3136e34215 MSL: Always use input_attachment_index for framebuffer fetch binding. 
--msl-decoration-binding would end up overriding the input attachment
index to binding which is very unexpected and broken.

a4a9b53b5b MSL: Always enable Outputs in vertex stages. 
Subsequent stages can legally attempt to read from these variables,
which causes compilation failure.

Always make sure we emit user outputs in vertex shaders if they are
active in the entry point.

c4ff129fe3 MSL: Handle reserved identifiers for entry point. 
We only considered invalid names, and overwrote the alias for the
function. The correct fix is to replace illegal names early, do the
reserved fixup, then copy back alias to entry point name.

Vulkan GLSL do not propgate the nonuniform qualifier.
