There're some duplicate code when adding hist entries. They are
different in that some have branch info or mem info but generally do
same thing. So introduce new struct hist_entry_iter and add callbacks
to customize each case in general way.
The new perf_evsel__add_entry() function will look like:
iter->prepare_entry();
iter->add_single_entry();
while (iter->next_entry())
iter->add_next_entry();
iter->finish_entry();
This will help further work like the cumulative callchain patchset.
