Refactor is_member_function_pointer to use is_function and not __member_function_traits.

Browse Source 
Replacing the dependancy on __member_function_traits with is_function allows
is_member_function_pointer to work more often. In particular it allows it to
work when we don't have variadic templates but the function has an arity > 3.
