Philip Reames a1cf015229 [InstCombine] (icmp sgt smin(PosA, B) 0) -> (icmp sgt B 0) 
When checking whether an smin is positive, we can move the comparison to one of the inputs if the other is known positive. If the known positive one is the min, then the other can't be negative. If the other is the min, then we compute the min.
