; This testcase contains a entire loop that should be removed. The only thing
; left is the store instruction in BB0. The problem this testcase was running
; into was that when the reg109 PHI was getting zero predecessors, it was
; removed even though there were uses still around. Now the uses are filled
; in with a dummy value before the PHI is deleted.
