[PATCH] D33136: [ValueTracking] Don't let isAddOfNonZero look at adds with a PHI node as input

What is the performance implication of this change-set? Have you done any performance testing? This seems to make the alias analysis very conservative. It is now going to find two non-equal numbers equal very easily.
