    c++: disable initializer_list transformation

    PRs 118673 and 118285 are wrong-code bugs with the transformation to build
    an initializer_list backing array from a static array of the initializer
    expressions; let's disable that transformation on the GCC 14 branch.

    gcc/cp/ChangeLog:

            * call.cc (convert_like_internal) [ck_list]: Stop using
            maybe_init_list_as_array for GCC 14.

    gcc/testsuite/ChangeLog:

            * g++.dg/tree-ssa/initlist-opt5.C: Add xfail.
