I think we should split this into two test: one for testing what debug info is generated (here in CodeGen) and another one for testing diagnostic behavior in Sema. The CodeGen test should be clean of diagnostics.

Another test I think we should add would be testing qualifier mismatches (where the bit-field is `const`-qualified to make sure that doesn't show up as a mismatch.
