; 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.
