    scheduling change in svn 115121.  The CriticalAntiDepBreaker had bad
    liveness information.  It was calculating the KillIndices for one scheduling
    region in a basic block, rescheduling that region so the KillIndices were
    no longer valid, and then using those wrong KillIndices to make decisions
    for the next scheduling region.  I've not been able to reduce a small
    testcase for this.  Radar 8502534.
