PR libstdc++/91910 fix data race in Debug Mode destructors
Fix data race when _Safe_iterator_base::_M_detach() runs concurrently with
the _Safe_container_base destructor.
PR libstdc++/91910
* src/c++11/debug.cc (_Safe_iterator_base::_M_detach()): Load pointer
atomically and lock the mutex before accessing the sequence.
(_Safe_local_iterator_base::_M_detach()): Likewise.
(_Safe_iterator_base::_M_reset()): Clear _M_sequence atomically.
From-SVN: r276184
