Port 0b3066b8 Original commit message: This implements a first prototype of stack unwinding for interpreted frames. The unwinding machinery performs a range-based lookup in the given handler table and potentially continues dispatching at the handler offset. Note that this does not yet correctly restore the context to the correct value when the handler is being entered.
