	* include/bits/cpp_type_traits.h
	(std::move_iterator): Delete declaration.
	(std::__is_move_iterator<move_iterator>): Move partial specialization...
	* include/bits/stl_iterator.h: ... here.
	(std::__miter_base): Overloads for std::reverse_iterator and
	std::move_iterator.
	* include/bits/stl_algobase.h (std::__miter_base): Provide default
	implementation.
