    libstdc++: Update expected error for debug/constexpr*_neg.cc tests
    
    We no longer hit a __builtin_unreachable() in these tests, so we need to
    update the dg-error patterns to match _Error_formatter::_M_error().
    
    We can also remove some dg-prune-output directives matching notes saying
    "in 'constexpr' expansion" because that's done globally in prune.exp.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/25_algorithms/copy/debug/constexpr_neg.cc: Adjust
            dg-error pattern.
            * testsuite/25_algorithms/copy_backward/debug/constexpr_neg.cc:
            Likewise.
            * testsuite/25_algorithms/equal/debug/constexpr_neg.cc:
            Likewise.
            * testsuite/25_algorithms/lower_bound/debug/constexpr_partitioned_neg.cc:
            Likewise.
            * testsuite/25_algorithms/lower_bound/debug/constexpr_partitioned_pred_neg.cc:
            Likewise.
            * testsuite/25_algorithms/lower_bound/debug/constexpr_valid_range_neg.cc:
            Likewise.
            * testsuite/25_algorithms/upper_bound/debug/constexpr_partitioned_neg.cc:
            Likewise.
            * testsuite/25_algorithms/upper_bound/debug/constexpr_partitioned_pred_neg.cc:
            Likewise.
            * testsuite/25_algorithms/upper_bound/debug/constexpr_valid_range_neg.cc:
            Likewise.
