; This test previously caused an infinite loop in legalize vector ops. Due to
; CSE triggering on the call to UpdateNodeOperands and the resulting node not
; being passed to LowerOperation. The add is needed to force the zext into a
; sext on that path. The shuffle keeps the zext alive. The xor somehow
; influences the zext to be visited before the sext exposing the CSE opportunity
; for the sext since zext of setcc is custom legalized to a sext and shift.
