libstdc++: Specialize std::pointer_traits<__normal_iterator<I,C>>
This allows std::__to_address to be used with __normal_iterator in
C++11/14/17 modes. Without the partial specialization the deduced
pointer_traits::element_type is incorrect, and so the return type of
__to_address is wrong.
A similar partial specialization is probably needed for
__gnu_debug::_Safe_iterator.

libstdc++-v3/ChangeLog:
* include/bits/stl_iterator.h (pointer_traits): Define partial
specialization for __normal_iterator.
* testsuite/24_iterators/normal_iterator/to_address.cc: New test.
