    libstdc++: suppress -Wdangling-reference with operator| [PR111410]

    It seems to me that we should exclude
std::ranges::views::__adaptor::operator|
    from the -Wdangling-reference warning.  It's commonly used when handling
    ranges.

            PR c++/111410

    libstdc++-v3/ChangeLog:

            * include/std/ranges: Add #pragma to disable -Wdangling-reference
with
            std::ranges::views::__adaptor::operator|.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Wdangling-reference17.C: New test.
