Wrap the original test in _LIBCPP_HAS_QUICK_EXIT so it only runs when we have quick_exit and add two new tests that check that when _LIBCPP_HAS_QUICK_EXIT is not defined then no definition of std::at_quick_exit or std::quick_exit are available. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@222298 91177308-0d34-0410-b5e6-96231b3b80d8
