0c0fd98322 MSL: Use var name instead of var-type name for flattened interface members.
This allows two variables of the same struct type to be flattened
into the same interface struct without a member name conflict.

Add shaders-msl/frag/in_block_with_multiple_structs_of_same_type.frag
unit test shader to demonstrate this.

ec054dad7f MSL: Support synthetic functions in function constants.
Emit synthetic functions before function constants.
Support use of spvQuantizeToF16() in function constants for numerical
behavior consistency with the op code.
Ensure subnormal results from OpQuantizeToF16 are flushed to zero per SPIR-V spec.

Adjust SPIRV-Cross unit test reference shaders to accommodate these changes.
Any MSL reference shader that inclues a synthetic function is affected,
since the location it is emitted has changed.

MSL: Fix '--msl-multi-patch-workgroup' out of bounds reads when dispatching more threads than control points (#1662)
* Fix '--msl-multi-patch-workgroup' cases where thread count exceeds data bounds

*Fix gl_PrimitiveID off by one error when computing last valid index
*Point gl_out to the last patch's data when threads exceed input data bounds
*Point patchOut to the last patch's data when threads exceed input data bounds

* Update MSL test expectations.

* Undo change to MSL multi-patch hull output bound checks

* Update MSL multi-patch test expectations.

ae9ca7d73c MSL: Fix copy of arrays to/from stage IO variables.
Need to take into account effective storage classes and whether or not
we target stage IO blocks since native arrays are conditionally enabled.

682a227f4b MSL: Make builtin argument type declaration context sensitive.
Sometimes we'll need array template, sometimes not 🤷.

c1edd35d57 MSL: Use spvUnsafeArray for builtin arrays after all.
It will get too messy to deal with constant initializers any other way,
so just deal with complexity in argument_decl instead ...

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.

46c48ee6b5 MSL: Rewrite how IO blocks are emitted in multi-patch mode.
Firstly, never flatten inputs or outputs in multi-patch mode.
The main scenario where we do need to care is Block IO.
In this case, we should only flatten the top-level member, and after
that we use access chains as normal.

Using structs in Input storage class is now possible as well. We don't
need to consider per-location fixups at all here. In Vulkan, IO structs
must match exactly. Only plain vectors can have smaller vector sizes as
a special case.
