There was confusion about the fullnames of type variables in nested generic classes. A type variable could be defined internally as
m.OuterClass.T, but it was sometimes accessed asm.T. The root cause was that the semantic analyzer didn't initialize the attribute that refers to the enclosing class consistently.Fixes #17596. Fixes #17630.
