For some reason, -fselective-scheduling is moving

(insn 19 16 22 2 (use (reg/i:SI 0 ax)) testcase.c:6 -1
     (nil))

around. This insn marks function return, so IMO should be at the function exit
all the time. -fschedule-insns (without -fselective-scheduling) leaves the insn
at the function exit. Is it OK to move this marker around?
