    Use cvt_op to save intermediate type operand instead of "subtle" vec_de=
st.

    When there're multiple operands in vec_oprnds0, vec_dest will be
    overwrited to vectype_out, but in multi_step_cvt case, cvt_type is
    expected. It caused an ICE when verify_gimple_in_cfg.

            save intermediate type operand instead of "subtle" vec_dest
            for case NONE.
