- 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

Handle this case in the SPIR-V reader, by seeing through the
intermediate alias type created for the strided array type.
