This is the rtl we used to produce:
(insn 144 69 75 8 (set (reg:CC 75 cr7)
        (reg:CC 30 r30 [125])) 336 {*movcc_internal1} (nil)
    (nil))  <-- this the insn which we are messing up now.

(jump_insn:HI 75 144 80 8 (set (pc)
        (if_then_else (ne (reg:CCFP 75 cr7)
                (const_int 0 [0x0]))
            (label_ref 115)
            (pc))) 527 {*rs6000.md:13676} (insn_list:REG_DEP_ANTI 67 (insn_list:REG_DEP_ANTI 69 
(insn_list:REG_DEP_ANTI 68 (nil))))
    (expr_list:REG_BR_PROB (
