    libstdc++: Add missing std::tuple constructor [PR114147]

    I caused a regression with commit r10-908 by adding a constraint to the
    non-explicit allocator-extended default constructor, but seemingly
    forgot to add an explicit overload with the corresponding constraint.

    libstdc++-v3/ChangeLog:

            PR libstdc++/114147
            * include/std/tuple (tuple::tuple(allocator_arg_t, const Alloc&)):
            Add missing overload of allocator-extended default constructor.
            (tuple<T1,T2>::tuple(allocator_arg_t, const Alloc&)): Likewise.
            * testsuite/20_util/tuple/cons/114147.cc: New test.
