        * include/debug/safe_unordered_base.h, safe_unordered_sequence.h,
        safe_unordered_sequence.tcc, safe_local_iterator.h,
        safe_local_iterator.tcc: New, support for unordered sequence safe
        local iterators.
        * include/Makefile.am: Add previous files.
        * include/Makefile.in: Regenerate.
        * include/debug/unordered_map, unordered_set: Implement
        _Safe_unordered_sequence and expose _Safe_local_iterator.
        * include/debug/safe_iterator.h, safe_iterator.tcc: Refactor
        _Safe_iterator::_M_get_distance static method to expose it as
        __get_distance function and use it in _Safe_local_iterator type.
        * include/debug/formatter.h: Add __msg_local_iter_compare_bad
        _Debug_msg_id enum entry to notify invalid comparison between local
        iterators from different buckets. Add _Parameter constructor from
        _Safe_local_iterator.
        * include/debug/functions.h: Add __valid_range overload for
        _Safe_local_iterator.
        * src/debug.cc: Add _Safe_unordered_sequence_base and
        _Safe_local_iterator_base methods implementations.
        * config/abi/pre/gnu.ver: Add export of some
        _Safe_unordered_sequence_base and _Safe_local_iterator_base methods.
        * testsuite/util/debug/checks.h: Add use_invalid_iterator function to
        simulate use of a singular iterator.
        * testsuite/util/debug/unordered_checks.h: New, several functions
        to simulate classic invalid usage of unordered sequence local
        iterators.
        * testsuite/23_containers/unordered_map/debug/
        use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc,
        use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc,
        invalid_local_iterator_compare_neg.cc: New.
        * testsuite/23_containers/unordered_multimap/debug/
        use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc,
        use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc,
        invalid_local_iterator_compare_neg.cc: New.
        * testsuite/23_containers/unordered_set/debug/
        use_erased_local_iterator_neg.cc, invalid_local_iterator_range_neg.cc,
        use_invalid_local_iterator_neg.cc, use_invalid_iterator_neg.cc,
        invalid_local_iterator_compare_neg.cc: New.
