2015-06-04 Ville Voutilainen <ville.voutilainen@gmail.com>
Add __is_nothrow_swappable and take it into use.
* include/bits/algorithmfwd.h (swap): Only declare for C++98 mode.
* include/bits/move.h (swap): Add constraints in C++11 and later.
* include/bits/stl_pair.h (swap): Use __is_nothrow_swappable
for the free swap function for pair.
* include/bits/stl_queue.h (swap): Use __is_nothrow_swappable
for the free swap functions for queue and priority_queue.
* include/bits/stl_stack.h (swap): Use __is_nothrow_swappable
for the free swap function for stack.
* include/debug/array (swap): Use __is_nothrow_swappable
for the free swap function for array.
* include/profile/array (swap): Likewise.
* include/std/array (swap): Likewise.
* include/std/tuple (_Tuple_impl::_M_swap): Use __is_nothrow_swappable.
* include/std/type_traits (__is_swappable_impl::__is_swappable,
__is_nothrow_swappable_impl, __is_nothrow_swappable): New.
* testsuite/20_util/is_nothrow_swappable/requirements/
explicit_instantiation.cc: New.
* testsuite/20_util/is_nothrow_swappable/requirements/typedefs.cc:
New.
* testsuite/20_util/is_nothrow_swappable/value.cc: New.
