[committed] libstdc++: Qualify functions used in tests

[Jonathan Wakely via Gcc-patches]

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.

Tested powerpc64le-linux. Committed to trunk.
