Slava Pestov dcc27ea819 Sema: Fix failure to emit diagnostic with some invalid member type references ...

There were two problems here:

- isUnsupportedMemberTypeReference() checked if the immediate parent type was
  an unbound generic type, but did not check for the parent of the parent, etc.

- The caller of isUnsupportedMemberTypeReference() had to re-check the
  various invalid conditions to determine what diagnostic to emit, and if
  none of those conditions matched it would just return an ErrorType without
  emitting a diagnostic.

Fix both of these by having isUnsupportedMemberTypeReference() return an
enum indicating what went wrong, and handle more cases.

Fixes <rdar://problem/67292528>.
