------- Additional Comments from Juan C. Montemayor <jmont at apple.com>
I added the changes suggested by Geoff. I decided to update both in
unwindCallFrame() and when an exception is thrown. I also added some asserts
where I removed updates to topCallFrame just to make sure that the callframes
at those points were correct. This patch has also been modified to work with
arm processors. Hopefully I didn't miss anything
