[PATCH] D30446: [IndVars] Do not branch on poison

As a generally good direction I like the idea of moving LFTR, and eventually even IV widening, forward to the LSR stage of the pipeline.
So, I'm ok with it as long as you do the normal amount of benchmark validation and  @mzolotukhin doesn't see any immediate performance issues with this approach.
