- When storing to sample_mask output, write to the 0th element - Only make a return struct if it has members - Adjust type signedness coercion when loading special builtins. - Adapt tests - Update expectations for end-to-end tests - Handle sample_mask with stride Input variables normally don't have layout. But they can have it up through SPIR-V 1.4. Handle this case in the SPIR-V reader, by seeing through the intermediate alias type created for the strided array type.
