Remove all shenanigans with propagation, and only consume nonuniform
qualifiers exactly where needed (last minute).

We have been interchanging spv and SPIRV_Cross_ for a while, which
causes weirdness since we don't explicitly ban SPIRV_Cross identifiers,
as these identifiers are generally used for interface variable
workarounds.

On MSL, the compiler refuses to allow access chains into a normal vector type.
What happens in practice instead is a read-modify-write where a vector type is
loaded, modified and written back.

The workaround is to convert a vector into a pointer-to-scalar before
the access chain continues to add the scalar index.
