Anna Thomas 7b360434ff [Loop Predication] Teach LP about reverse loops 
Summary:
Currently, we only support predication for forward loops with step
of 1.  This patch enables loop predication for reverse or
countdownLoops, which satisfy the following conditions:
   1. The step of the IV is -1.
   2. The loop has a singe latch as B(X) = X <pred>
latchLimit with pred as s> or u>
   3. The IV of the guard is the decrement
IV of the latch condition (Guard is: G(X) = X-1 u< guardLimit).

This patch was downstream for a while and is the last series of patches
that's from our LP implementation downstream.
