    gimplify: Gimplify value in gimplify_init_ctor_eval_range [PR98353]

    gimplify_init_ctor_eval_range wasn't gimplifying value, so if it wasn't
    a gimple val, verification at the end of gimplification would ICE (or w=
ith
    release checking some random pass later on would ICE or misbehave).
