Oh, seems that more checks are needed to prevent unnamed fields from occurring in enums.

Don't ICE on anonymous struct in enum variant

Fixes rust-lang#121446

Computing `adt_def` for the anon struct calls `adt_def` on the parent to find its repr. If the parent is a non-item (e.g. an enum variant) we should have already emitted at least one error, so we just use the repr of the anonymous struct to avoid an ICE.
