    libstdc++: Make operator== for std::tuple convert to bool [PR119545]

    The boolean-testable requirements don't require the type to be copyable,
    so we need to convert to bool before it might need to be copied.

    libstdc++-v3/ChangeLog:

            PR libstdc++/119545
            * include/std/tuple (operator==): Convert comparison results to
            bool.
            * testsuite/20_util/tuple/comparison_operators/119545.cc: New
            test.
