Thanks.  In that case, can we get at least following into GCC 13,
another spot that handles in IPA just BUILT_IN_UNREACHABLE and
not BUILT_IN_UNREACHABLE_TRAP?

Bootstrapped/regtested on x86_64-linux and i686-linux.

        * ipa-prop.cc (try_make_edge_direct_virtual_call): Handle
        BUILT_IN_UNREACHABLE_TRAP like BUILT_IN_UNREACHABLE.
