*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

* Update MSL test expectations.

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 ...

7b9a591aa7 MSL: Hoist out to_tesc_invocation_id() in more places.

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.
