Partially committed revision 187927.

I needed to move the implementation of addresssof into <__functional_base> to keep the header dependency non-circular.

This treatment isn't needed in <future> because the type having its address taken is:

    typename aligned_storage<sizeof(_Rp), alignment_of<_Rp>::value>::type

This is a type that libc++ controls, and will never overload the operator&() on it.

Thanks,
