cpu: pred: Local Predictor Reset in Tournament Predictor
When a branch gets squashed, it's speculative branch predictor state should get rolled back in squash(). However, only the globalHistory state was being rolled back. This patch adds (at least some) support for rolling back the local predictor state also. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
