3976         Use get_address_mode.
3977         (get_adjusted_src): Remove.
3978         (add_stores): Don't call it.  Never reuse expr SET.  Don't add extra

3983         initialization to the beginning of the function from end.  Pass
3984         CSELIB_RECORD_MEMORY | CSELIB_PRESERVE_CONSTANTS to cselib_init.
3985         If !frame_pointer_needed, call vt_stack_adjustment before mos
