    libstdc++: Initialize std::normal_distribution::_M_saved [PR 99536]

    This avoids a false positive -Wmaybe-uninitialized warning, by
    initializing _M_saved on construction.

    libstdc++-v3/ChangeLog:

            PR libstdc++/99536
            * include/bits/random.h (normal_distribution): Use
            default-initializer for _M_saved and _M_saved_available.
