        * config/i386/i386-features.c (convert_scalars_to_vector):
        Update crtl->stack_realign_needed, crtl->stack_realign_tried and
        crtl->stack_realign_processed.  Update crtl->drap_reg by calling
        targetm.calls.get_drap_rtx.  If drap_rtx is non-null then
        Update crtl->args.internal_arg_pointer and call fixup_tail_calls.
