    libstdc++: Fix error handling in filesystem::equivalent [PR113250]

    This patch made std::filesystem::equivalent correctly throw an exception
    when either path does not exist as per [fs.op.equivalent]/4.

            PR libstdc++/113250

            * src/c++17/fs_ops.cc (fs::equivalent): Use || instead of &&.

            * testsuite/27_io/filesystem/operations/equivalent.cc: Handle
            error codes.
            * testsuite/experimental/filesystem/operations/equivalent.cc:
