; Interesting test case where %tmp1220 = xor i32 %tmp862, %tmp592 and
; %tmp1676 = xor i32 %tmp1634, %tmp1530 have zero demanded bits after
; TargetLoweringOpt pass. These are changed to undef and in turn
; DAGCombiner optimization pass. These are changed to undef and in turn
; the successor shl(s) become shl undef, 1. This pattern then matches
; shl x, 1 -> add x, x. add undef, undef doesn't guarentee the low
; order bit is zero and is incorrect.
