fitzgen opened issue #5270:

This would let us reuse existing immediate-encoding optimizations for rewriting value >= C + 1 into value > C when C + 1 is odd. In general this is pretty nice to have, since it turns a four instruction sequence into a two instruction sequence.

Follow up issue from:

In the future, we could try and "rotate" const <= value into value >= const and then go through this same optimization path so that we don't need to duplicate the rules but with tiny tweaks. I opted not to do that in this PR and removed the buggy optimizations to just get this land-able.
