Re: s390, the condition includes ACCESS_REG_P test, which is for a0/a1 hard
reg, so I think just adding reload_completed test to the splitters wouldn't be
a problem, and if we introduce peephole2_completed, we might deal with it the
same way (one splitter changed into define_peephole2, the other guarded with
peephole2_completed).
