Please add some test coverage that we properly diagnose this situation.
I think we'll produce a diagnostic mentioning `bit_cast`, which is probably not
what we want here. Maybe the simplest thing to do to fix that would be to
replace `bit_cast` with `bit cast` in all the diagnostics. That seems at least
as good for the `std::bit_cast` / `__builtin_bit_cast` case, and better for the
vector cast case.
