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
