; This testcase, obviously distilled from a large program (bzip2 from Specint2000)
; caused instcombine to fail because it got the same instruction on it's worklist
; more than once (which is ok), but then deleted the instruction.  Since the inst
; stayed on the worklist, as soon as it came back up to be processed, bad things
; happened, and opt asserted.
