Yes, I'll have a patch for you. Though I've come to the conclusion
that introducing a new regset is probably a better way to solve it.
We can then also expose orig_x0 at the same time and give it sane semantics
(there's some problems with the way it works currently - I'll write it up
together with the patch).
