PR target/42895
* doc/tm.texi (ADJUST_REG_ALLOC_ORDER): Renamed from
ORDER_REGS_FOR_LOCAL_ALLOC. All instances of this macro changed.
(HONOR_REG_ALLOC_ORDER): Describe new macro.
* ira.c (setup_alloc_regs): Use ADJUST_REG_ALLOC_ORDER if defined.
* ira-color.c (assign_hard_reg): Take prologue/epilogue costs into
account only if HONOR_REG_ALLOC_ORDER is not defined.
* config/arm/arm.h (HONOR_REG_ALLOC_ORDER): Define.
* system.h (ORDER_REGS_FOR_LOCAL_ALLOC): Poison.
