    c++: empty base constexpr -fno-elide-ctors [PR105245]

    The patch for 100111 extended our handling of empty base elision to the
case
    where the derived class has no other fields, but we still need to make sure
    that there's some initializer for the derived object.

    gcc/cp/ChangeLog:

            * constexpr.c (cxx_eval_store_expression): Build a CONSTRUCTOR
            as needed in empty base handling.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/constexpr-empty2.C: Add -fno-elide-constructors.
