; 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.
