stl_algo.h (__rotate<_RandomAccessIterator>): Don't qualify __tmp as const, _ValueType is not necessarily Assignable.

	* include/bits/stl_algo.h (__rotate<_RandomAccessIterator>):
	Don't qualify __tmp as const, _ValueType is not necessarily
	Assignable.
	* include/bits/stl_algobase.h (swap, __iter_swap<false>):
	Likewise, as an harmless extension.
