Philip Reames 5a637cbdc7 [LoopPred] Extend LFTR normalization to the inverse EQ case ...

A while back, I added support for NE latches formed by LFTR.  I didn't think that quite through, as LFTR will also produce the inverse EQ form for some loops and I hadn't handled that.  This change just adds handling for that case as well.
