Yeah that sounds good - there are a number of other cores that have it but are
not marked, but I don't have a list. The features was added after the cores
were added and it didn't add them to all. Adding for V2 is a good start.
It can change the way PACBTI is emitted, I believe to make it more efficient
and shouldn't be an issue so long as the instructions do throw exceptions.
