[PATCH] D21299: [Codegen Prepare] Swap commutative binops before splitting branch condition.

Although this is target independent, I have added a feature flag to guard this change. It is currently enabled only for Kryo because I tested only on this target. If this is profitable for other targets, we can add the feature flag to those targets.

Renato, is this along the lines of what you were suggesting?
