It's not about the diagnostic, it's about clang crashing in constant evaluation
because the type of the case stmt expression is wrong:

I don't know if the conversions only need to happen for well-formed code or
not. If not, we should instead mark the case stmt as having errors I guess, but
just letting it through like that trips up a couple of places
