When implementing C23 enums with fixed underlying types I tried to ensure that
enums with underlying type bool were handled consistently with bool (cf. bug
96496 where they're not always handled

I think we need to reject all integral types whose operation range doesn't
match the corresponding integer mode range. For enums it depends on the
language standard, in general I'd say it's not wanted.

So it turns out before GCC 9, using enum vectors would ICE (PR 87286).
It was asked then if we should reject them but there was no answer to question
that but rather just fixing the ICE alone.
