gcc16-pr122185.patch
You can't provide a valid testcase for this, because it can only ICE on invalid
ones. In particular the -ffold-simple-inlines code was just assuming standard
conforming std::move, std::forward, std::forward_like, std::addressof,
std::as_const, std::to_underlying and std::__addressof with same behavior as
std::addressof.
The INDIRECT_TYPE_P && INDIRECT_TYPE_P check was actually correct before for
preventing folding (and possibly ICEs or weird stuff) on invalid definitions of
these. Now, std::to_underlying doesn't satisfy that and guess that is why it
was removed, in that case it wants to convert ENUMERAL_TYPE to INTEGRAL_TYPE_P.
So, this patch checks that too.
