tuple (tuple<>::operator=(tuple&&)): Specify as noexcept.

2011-05-19  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/std/tuple (tuple<>::operator=(tuple&&)): Specify as
        noexcept.
	(__get_helper): Likewise.
	(_Head_base<>::_M_head, _Tuple_impl<>::_M_head, _M_tail): Likewise.
	* include/bits/move.h (swap): Likewise.
	* include/bits/algorithmfwd.h (swap): Adjust.
	* include/bits/stl_pair.h (pair<>::operator=(pair&&)): Spec noexcept.
	* testsuite/util/testsuite_allocator.h (uneq_allocator): In C++0x
	mode, prefer delete to access control to make the type not copy
	assignable.
	* testsuite/util/testsuite_tr1.h: Add test classes.
	* testsuite/20_util/tuple/noexcept_swap.cc: New.
	* testsuite/20_util/tuple/noexcept_move_assign.cc: Likewise.
	* testsuite/25_algorithms/reverse/moveable.cc: Likewise, prefer
