update result_of and reference_wrapper

In the current draft, reference_wrapper invocation requires Callable, which
means it should not work for pointers to members. The same is true of
result_of, which determines the result of an expression that isn't valid syntax
for pointers to members.

That said, here's a patch that updates result_of and reference_wrapper to work
for pointers to members as well as callable types, using result_of in place of
the Callable concept.  If result_of and reference_wrapper really shouldn't work
for pointers to members then this patch would be much simpler, and there's no
need for __invoke() either.
