We need partial specializations of _Mem_fn for member function types
that are noexcept(true). Rather than relying on deducing the
exception-specification (which is not supported by Clang yet) I've
just added some more uses of the macro that generates the partial
specializations.

	PR libstdc++/80478
	* include/std/functional (_Mem_fn_traits_base): Add specializations
	for noexcept member function types.
	* testsuite/20_util/function_objects/mem_fn/80478.cc: New test.

Tested powerpc64le-linux, committed to trunk. Backport to gcc-7-branch
coming shortly.
