    More conservatively report status from LoopIdiomRecognize

    Being "precise" here is getting us into trouble with one of the
    EXPENSIVE_CHECKS buildbots, see [1].  Rather than reporting IR additions
that
    later get rolled back as "no change", instead we now conservatively report
that
    there was.
