0bbe041411 MSL: Remove dubious workaround code in unpack_expression.
From UE4 review, does not cause any changes in test output, and should
only change output if we were unpacking arrays or something like that,
which we don't support.

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.

fa011f8547 MSL: Declare arrays with proper type wrapper.

2745959646 MSL: Deal with chained access chains for tessellation IO variables.
Need to specially deal with this since we might have to split up access
chain and deal with indexing into IB struct.

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.

bac2c34590 MSL: Slight cleanup in emit_tessellation_access_chain.
Hoist out some conditionals and make it clear that we go into this path
if strip_array is used when declaring resources, i.e. there was no
explicit unflatten step.

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.

028ffc26dd MSL: Report tess input array failures more accurately.

not fail with opaque "bad cast" error.

2767257adc MSL: Do not declare array of UBO/SSBO as spvUnsafeArray<T>.

53d0dd6741 MSL: Support option for treating 1D textures as 2D textures of height 1.
Fixes from feedback.

Change vertical sampling of 1D texture from 0.0 to 0.5 to avoid edge conditions.

4b5c6c188c MSL: Support option for treating 1D textures as 2D textures of height 1.
Add CompilerMSL::Options::texture_1D_as_2D.

Metal imposes significant restrictions on 1D textures, including not being
renderable, clearable, or permitting mipmaps. This option allows SPIR-V 1D
textures to be treated as 2D textures to permit this additional behaviour.
App must of course supply the textures to Metal as 2D textures.

4ac12594c9 MSL: Be a little clearer how needs_base_vertex_idx is implemented.
There is an implicit tristate with {-1, 0, +1} values, but it was not
obvious how this was supposed to work before studying the implementation,
so refactor into a tristate enum class.

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.
