public int getBranched() {

Get the index of the last (branch) op executed

<p>
The behavior here is a bit strange for compatibility with
{@link EmulateInstructionStateModifier}. If the p-code program (likely derived from a machine
instruction) completed with fall-through, then this will return -1. If it completed on a
branch, then this will return the index of that branch.

@return the last index executed
