	* include/bits/stl_algobase.h (__copy_trivial): Remove.
	(__copy_aux2): Rewrite as __copy_aux to use __is_pointer,
	__is_trivially_copyable, __are_same and __copy::copy.
	(__copy): Rewrite as a class template and two specializations.
	(__copy_ni2): Simplify, just call __copy_aux.

	* include/bits/stl_algobase.h (__copy_backward_aux): Add __are_same
	check.
	* testsuite/25_algorithms/copy/1.cc, 2.cc, 3.cc, 4.cc: Test also
	for destination value type != source value type.
