    PR rtl-optimization/52804
    * reload1.c (reload_reg_reaches_end_p): Check whether successor
    reload with type RELOAD_FOR_INPUT_ADDRESS kills reload register
    of current one with type RELOAD_FOR_INPADDR_ADDRESS.
    Same stands for reloads with type RELOAD_FOR_OUTPUT_ADDRESS and
    RELOAD_FOR_OUTADDR_ADDRESS.
