Before CSE:
(insn 13 2 5 2 t.c:8 (set (reg:SI 119)
(plus:SI (reg/f:SI 113 sfp)
(const_int 8 [0x8]))) -1 (nil))
(insn 5 13 6 2 t.c:8 (set (reg:SI 3 3)
(reg:SI 119)) 332 {*movsi_internal1} (nil))
...
(insn 14 6 7 2 t.c:9 (set (reg:SI 120)
(plus:SI (reg/f:SI 113 sfp)
(const_int 8 [0x8]))) -1 (nil))
(insn 7 14 8 2 t.c:9 (set (reg:SI 3 3)
(reg:SI 120)) 332 {*movsi_internal1} (nil))
And then after CSE, we remove the adds but we should have moved the adds into
the move.
