We do the same elsewhere (e.g. in parser.name when a name is missing).
This ensures functions have a (dummy) name and a non-nil type.
Avoids a crash in the type-checker (verified manually).
A test was added here (rather than the type checker) because type-
checker tests are shared between types2 and go/types and error
recovery in this case is different.
Fixes #63835.
