stl_construct.h (_Destroy): New three-argument overload that takes an allocator argument.

	* include/bits/stl_construct.h (_Destroy): New three-argument
	overload that takes an allocator argument.  Another inline
	three-argument overload that takes std::allocator and dispatches
	to the two-argument version.
	* include/bits/stl_uninitialized.h (__uninitialized_fill_n_aux):
	Change return type to void to match uninitialized_fill_n.
	(__uninitialized_copy_a_): New function.  Like uninitialized_copy
	except that it takes an allocator and uses it for construct and
	destroy.  If the allocator is std::allocator, dispatches to
	uninitialized_copy.
	(__uninitialized_fill_a): Likewise.
	(__uninitialized_fill_n_a): Likewise.
	(__uninitialized_copy_copy): Give it an allocator argument.
	(__uninitialized_fill_copy): Likewise.
	(__uninitialized_copy_fill): Likewise.
	* include/bits/deque.tcc: Use new forms defined in stl_construct.h
	and stl_uninitialized.h.  Replace use of single-argument _Construct
	and _Destroy with use of allocator's construct and destroy methods.
	* include/bits/list.tcc: Likewise.
	* include/bits/stl_deque.h: Likewise.
	* include/bits/stl_list.h: Likewise.
	* include/bits/stl_tree.h: Likewise.
	* include/bits/stl_vector.h: Likewise.
	* include/bits/vector.tcc: Likewise.
	* include/ext/hashtable.h: Use rebind so that allocator_type
	has correct type for a container's allocator.  Replace use of
	single-argument _Construct and _Destroy with use of allocator's
	construct and destroy methods.
	* include/ext/memory (__uninitialized_copy_n_a): New function.
	Like uninitialized_copy_n except that it takes an extra parameter,
	an allocator, and uses it for construct and destroy operations.
	* include/ext/rope: Use new forms defined in stl_construct.h,
	stl_uninitialized.h, and ext/memory.  Replace use of single-argument
	_Construct and _Destroy with allocator construct and destroy methods.
	* include/ext/ropeimpl.h: Likewise.
	* include/ext/slist.h: Likewise.
	* testsuite/testsuite_allocator.h (check_construct_destroy): New.
	* testsuite/testsuite_allocator.cc (check_construct_destroy): New.
	* testsuite/23_containers/deque/check_construct_destroy.cc: New.
	* testsuite/23_containers/list/check_construct_destroy.cc: New.
	* testsuite/23_containers/set/check_construct_destroy.cc: New.
	* testsuite/23_containers/vector/check_construct_destroy.cc: New.
	* testsuite/ext/hash_check_construct_destroy.cc: New.
	* testsuite/ext/slist_check_construct_destroy.cc: New.
