Stephen White 0b39270e01 GLSL: move entry point handling to CanonicalizeEntryPointIO transform.
Move builtin_to_string() and builtin_type() to
the CanonicalizeEntryPointIO transform. Use the former to
rename entry point IO variables to the gl_ names, and the latter
to cast values to the correct type.
