    libstdc++: Use memcmp to optimize std::bitset::_M_is_equal() [PR113807]

    As noted in the PR the compiler doesn't seem able to do this on its own,
    so we get better code at all optimization levels by using memcmp.

    libstdc++-v3/ChangeLog:

            PR libstdc++/113807
            * include/std/bitset (bitset::_M_is_equal()): Use memcmp to
            optimize operator==.
