re PR rtl-optimization/52804 (IRA/RELOAD allocate wrong register on ARM for cortex-m0)

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.
