Namhyung Kim b1dd443296 perf annotate: Add basic support to event group view
Add --group option to enable event grouping.  When enabled, all the
group members information will be shown with the leader so skip
non-leader events.

It only supports --stdio output currently.  Later patches will extend
additional features.

 $ perf annotate --group --stdio
