    c++: constexpr trivial -fno-elide-ctors [PR104646]

    The constexpr constructor checking code got confused by the expansion o=
f a
    trivial copy constructor; we don't need to do that checking for default=
ed
    ctors, anyway.

            PR c++/104646

    gcc/cp/ChangeLog:

            * constexpr.cc (maybe_save_constexpr_fundef): Don't do extra
            checks for defaulted ctors.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/constexpr-fno-elide-ctors1.C: New test.=
