For CPSR tracking?

It seems like dangerous business to depend on the CPSR liveness info when it can't be verified because liveness for other registers is in tatters.

I am not sure how to handle that. Ideally, I would like to recompute CPSR liveness from the code instead of depending on outdated cached information.
