predict-lop-exit-1.C: Update template for new predictor name.
* g++.d/predict-lop-exit-1.C: Update template for new predictor name.
* g++.d/predict-lop-exit-2.C: Update template for new predictor name.
* g++.d/predict-lop-exit-2.C: Update template for new predictor name.
* predict.def (PRED_LOOP_EXTRA_EXIT): Define.
* predict.c (predict_iv_comparison): Also check PRED_LOOP_EXTRA_EXIT.
(predict_extra_loop_exits): Use PRED_LOOP_EXTRA_EXIT instead of
PRED_LOOP_EXIT.
