Putting 'perf diff' command back on track with the 'latest'
evsel hists changes. Each evsel has its own 'hists' object
gathering stats for the particular event.
While currently counts are accumulated for the whole session
regardless of the events diversification within compared
sessions.
The 'perf diff' command now outputs all matching events within
compared sessions (with event name specified). The per event
diff output stays the same.
