	* include/debug/functions.h (_Insert_range_from_self_is_safe<>):
	New, indicate container types supporting self range insertion in
	GNU implementation.
	(__foreign_iterator): New, check if an iterator points to a given
	sequence.
	* include/debug/macros.h (__glibcxx_check_insert_range): Add check
	using __foreign_iterator.
	(__gibcxx_check_insert_range_after): Likewise.
	* include/debug/string (_Insert_range_from_self_is_safe<>):
	Partially specialized to mark __gnu_debug::basic_string<> as
	supporting self range insert.
	* include/debug/list (_Insert_range_from_self_is_safe<>):
	Partially specialized to mark std::list as supporting self range
	insert if _GLIBCXX_DEBUG_PEDANTIC is not defined.

	* src/c++11/debug.cc (_S_debug_messages): Add

	* testsuite/23_containers/deque/debug/insert5_neg.cc: New.
	* testsuite/23_containers/vector/debug/insert5_neg.cc: Likewise.
