Just bumping my patch, probably it got lost over the weekend.

> Hello reviewers
> The attached patch refactors the disassembly of Thumb IT instructions. The IT
> state is pushed to a stack and then popped and applied to subsequent
> instructions in the IT block.
> The old implementation used an insertion at the front of a vector which is
> linear in complexity to the size of the vector. My patch replaces it with an
> actual stack, and encapsulates it in a class.
> Please review.
> Thanks
