  -----------
  Reject operations between vectors and enum types.

There are some lookup oddities with these as reported in PR45780, and
GCC doesn't support these behaviors at all.  To be more consistent with
GCC and prevent the crashes caused by our lookup issues, nip the problem
in the bud and prohibit enums here.
