Detailed Description

This node is the base class for sequential/in-order min/max selections.

Note that their fundamental difference from SCEVMinMaxExpr's is that they are early-returning upon reaching saturation point. I.e. given 0 umin_seq poison, the result will be 0, while the result of 0 umin poison is poison.
