Subject: [PATCH] libstdc++: Fix several _GLIBCXX_DEBUG tests

libstdc++-v3/ChangeLog:

	* testsuite/23_containers/array/debug/back2_neg.cc: target c++14 because assertion
	for constexpr is disabled in C++11.
	* testsuite/23_containers/array/debug/front2_neg.cc: Likewise.
	* testsuite/23_containers/array/debug/square_brackets_operator2_neg.cc: Likewise.
	* testsuite/23_containers/vector/debug/multithreaded_swap.cc: Include <memory>
	for shared_ptr.
