stl_map.h (map()): Make default.

2016-10-26  François Dumont  <fdumont@gcc.gnu.org>

	* include/bits/stl_map.h (map()): Make default.
	* include/bits/stl_multimap.h (multimap()): Likewise.
	* include/bits/stl_multiset.h (multiset()): Likewise.
	* include/bits/stl_set.h (set()): Likewise.
	* include/bits/stl_tree.h (_Rb_tree_impl()): Add conditional noexcept.
	(_Rb_tree()): Make default.
