Log:
        PR libstdc++/60333
        * include/std/type_traits (__make_unsigned_selector<_Tp, false, true>):
        Handle enumeration types larger than sizeof(long).
        (__make_signed_selector<_Tp, false, true>): Find unsigned type then
        make it signed.
        * testsuite/20_util/declval/requirements/1_neg.cc: Adjust dg-error.
        * testsuite/20_util/make_signed/requirements/typedefs_neg.cc:
        Likewise.
        * testsuite/20_util/make_signed/requirements/typedefs-3.cc: New.
        * testsuite/20_util/make_unsigned/requirements/typedefs_neg.cc: Adjust
        dg-error.
        * testsuite/20_util/make_unsigned/requirements/typedefs-3.cc: New.
