--- Comment #1 from Kaelyn Takata <rikka at google.com> ---
It looks like this was fixed back in r191449. As of r236883, the simplified
test case:

struct Sema {
  enum CXXSpecialMember {
    CXXDefaultConstructor,
    CXXCopyConstructor,
    CXXMoveConstructor,
    CXXCopyAssignment,
    CXXMoveAssignment,
    CXXDestructor,
    CXXInvalid
  };
};
void test(Sema::CXXSpecialMember CSM) {
  switch (CSM) {
    case CXXDefaultConstructor: break;
    case CXXCopyConstructor: break;
    case CXXMoveConstructor: break;
    case CXXCopyAssignment: break;
    case CXXMoveAssignment: break;
    case CXXDestructor: break;
    case CXXInvalid: break;
  }
}

yields:

    case CXXDefaultConstructor: break;

7 errors generated.

While more verbose than condensing everything down into one diagnostic, I
suspect it is the best that can be done without a major reworking of at least
the diagnostics machinery.
