perf diff: Start moving to support matching more than two hists
We want to match more than two hists, so that we can match more than two
perf.data files and moreover, match hist_entries (buckets) in multiple
events in a group.
So the "baseline"/"leader" will instead of a ->pair pointer, use a
list_head, that will link to the pairs and hists__match use it.
Following that perf_evlist__link will link the hists in its evsel
groups.
