Subject: [PATCH 07/14] perf ui/hist: Add support for event group view
From: Namhyung Kim <namhyung.kim@....com>
Show group members' overhead also when showing the leader's if event
group is enabled. Use macro for defining hpp functions which looks
almost identical.
Thanks to Arnaldo for suggesting a better way to print group members
without allocating temporary array.
