    libstdc++: Qualify functions used in tests
    
    These tests rely on ADL for some functions, probably unintentionally.
    The calls only work because the iterator wrappers derive from
    std::iterator and so namespace std is an associated namespace.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/25_algorithms/inplace_merge/constrained.cc: Qualify
            call to ranges::next.
            * testsuite/25_algorithms/is_sorted/constrained.cc: Likewise.
            * testsuite/25_algorithms/is_sorted_until/constrained.cc:
            Likewise.
            * testsuite/25_algorithms/swap_ranges/1.cc: Qualify call to
            swap_ranges.
