    libstdc++: Fix invalid constexpr function in C++11 mode [PR 99985]

    I keep forgetting that a constexpr function in C++11 has to be a single
    return statement.

    libstdc++-v3/ChangeLog:

            PR libstdc++/99985
            * include/bits/hashtable.h (_Hashtable::_S_nothrow_move()): Fix
            to be a valid constexpr function in C++11.
            * testsuite/23_containers/unordered_set/cons/99985.cc: New test.
