For some reason, IRA chooses different reload registers.

These are differences in chosen reload registers:
-Reloads for insn # 583
+Reloads for insn # 697
Reload 0: reload_out (DI) = (reg:DI 789)
GENERAL_REGS, RELOAD_FOR_OUTPUT (opnum = 0)
reload_out_reg: (reg:DI 789)
- reload_reg_rtx: (reg:DI 28 $28)
+ reload_reg_rtx: (reg:DI 0 $0)
Reload 1: reload_in (DI) = (reg/v/f:DI 81 [ endp ])
GENERAL_REGS, RELOAD_FOR_INPUT (opnum = 2)
reload_in_reg: (reg/v/f:DI 81 [ endp ])
- reload_reg_rtx: (reg:DI 28 $28)
+ reload_reg_rtx: (reg:DI 0 $0)
[...]
-Reloads for insn # 475
+Reloads for insn # 556
Reload 0: reload_in (SI) = (const_int -1894007588 [0xffffffff8f1bbcdc])
GENERAL_REGS, RELOAD_FOR_INPUT (opnum = 2), can't combine
reload_in_reg: (reg:SI 795)
