The code in #20162 contains an embedded interface. It didn't get dowidth'd by the frontend, and during DWARF generation, ngotype asked for a string description of it, which triggered a request for the number of fields in the interface, which triggered a dowidth, which is disallowed in the backend. The other changes in this CL are to support the test.
