PR c++/92009 - ICE with punning of typeid.
There were two issues in this PR:
1) We were crashing in is_really_empty_class because we say that the
internal RTTI types are classes, but never gave them TYPE_BINFO.
2) We were allowing the cast to a different pointer type because STRIP_NOPS
in cxx_fold_indirect_ref ignored REINTERPRET_CAST_P.
* rtti.c (get_tinfo_desc): Call xref_basetypes.
* constexpr.c (cxx_fold_indirect_ref): Don't strip
REINTERPRET_CAST_P.
