b77be9f347 Update graphics robust access results
The robust access code was fixed to use a signed clamp which generates
different results in the SPIR-V cross test.

a3fe9756d2 MSL: Support ClipDistance as an input stage variable.
MSL does not support this, so we have to emulate it by passing it around
as a varying between stages. We use a special "user(clipN)" attribute
for this rather than locN which is used for user varyings.

b85ab5f5ff MSL: Fix automatic binding allocation for image atomic buffers.
The Primary decoration was used by the atomic buffer, causing the
texture binding to be potentially overlapping with other resources.

1d5eba67f8 MSL: Remove hacky workaround for patch constant passing.
There was a hack to workaround a bug in DXC where control point -> patch
constant phase was passed in Function storage, but we have to use
Workgroup here. We will not support these kinds of hacks for invalid
SPIR-V, so hack the reference files to use the "proper" fix and remove
the hack for time being.

e1919744e9 Hack some constants in UE4 tests.
Need to make output 100% exact for MSVC and GCC libc testing, but they are 1 ULP
off when converting fp32 to string in some weird corner cases.
Roundtrip should be correct though, but that outside the scope of
SPIRV-Cross.

648dfa5070 MSL: Ensure stable output for access chain CFG workarounds.
We had output dependent on complex_continue being set, but setting that
flag was dependent on unordered_set declaration order. Make it invariant
to ordering and change the implementation so it knows about the new
temporary hoisting for access chains.

fa011f8547 MSL: Declare arrays with proper type wrapper.
Need to construct with value type spvUnsafeArray<T, N>({ elem0, elem1 })
to make array initialization work in complex scenarios.

27d6d45671 MSL: Rewrite tessellation_access_chain.
To support loading array of array properly in tessellation, we need a
rewrite of how tessellation access chains are handled.

The major change is to remove the implicit unflatten step inside
access_chain which does not take into account the case where you load
directly from a control point array variable.

We defer unflatten step until OpLoad time instead.
This fixes cases where we load array of {array,matrix,struct}.

Removes the hacky path for MSL access chain index workaround.

d0953f6e4c MSL: Do not declare variables which will not be unflattened.
Non-patch arrays of IO variables in tesc/tese have their array index
stripped, and access chains are specially handled, we shouldn't attempt
to create "normal" arrays of these.

3b5c4c7316 Implement constant empty struct correctly on all backends.
MSL actually supports empty structs, so enable that path as well.

d1479f871a MSL: Do not generate UnsafeArray<> for any array inside buffer objects.
This avoids a lot of huge code changes.
Arrays generally cannot be copied in and out of buffers, at least no
compiler frontend seems to do it.

Also avoids a lot of issues surrounding packed vectors and matrices.
