References can't be CV qualified, so the REFERENCE_TYPE check seems

True. I did it because that matches the semantics of the cast
according to the standard, but it isn't needed here. Is it worth
keeping anyway, to avoid a redundant call to cv_unqualified?
I don't think it's worth checking.
It also occurs to me that checking for !CLASS_TYPE_P (type) isn't
needed in build_const_cast_1 because you can't const_cast to a class
type, only reference or pointer types.
true.
