I'd like to go ahead and get this in. I have another follow up patch to teach cannotBeOrderedLessThanZeroImpl to walk through ExtractElement too. The original place I saw this was two fabs on elements extracted from a vector.

But I think you're probably right that we should probably improve pattern matching for FP here.
