stl_vector.h (vector<>::push_back<>(_Args...), [...]): Add. 

2007-11-05  Chris Jefferson  <chris@bubblescope.net>
	    Paolo Carlini  <pcarlini@suse.de>

	* include/bits/stl_vector.h (vector<>::push_back<>(_Args...),
	emplace<>(iterator, _Args...), insert(iterator, _Tp&&),
	_M_insert_aux<>(iterator, _Args&&...)): Add.
	* include/bits/vector.tcc (insert(iterator, value_type&&),
	emplace<>(iterator, _Args...), _M_insert_aux<>(iterator, _Args&&...)):
	Define.
	(_M_fill_insert(iterator, size_type, const value_type&),
	_M_range_insert(iterator, _ForwardIterator, _ForwardIterator,
	std::forward_iterator_tag)): Use __uninitialized_move_a,
	_GLIBCXX_MOVE_BACKWARD3 when possible.
	* include/bits/stl_uninitialized.h (__uninitialized_move_a): Add.
	* include/debug/vector (vector<>::push_back<>(_Args...),
