Log:
	PR sanitizer/65400
	* ipa-split.c (find_return_bb): Allow TSAN_FUNC_EXIT internal
	call in the return bb.
	(find_split_points): Add RETURN_BB argument, don't call
	find_return_bb.
	(split_function): Likewise.  Add ADD_TSAN_FUNC_EXIT argument,
	if true append TSAN_FUNC_EXIT internal call after the call to
	the split off function.
	(execute_split_functions): Call find_return_bb here.
	Don't optimize if TSAN_FUNC_EXIT is found in unexpected places.
	Adjust find_split_points and split_function calls.

	* c-c++-common/tsan/pr65400-1.c: New test.
	* c-c++-common/tsan/pr65400-2.c: New test.
