Create some branch counters in per callchain list entry. Each counter is for a branch flag. For example, predicted_count counts all the *predicted* branches. The counters get updated by processing the callchain cursor nodes. It also provides functions to retrieve or print the values of counters in callchain list. Besides the counting for branch flags, it also counts and returns the average number of iterations.
