Namhyung Kim 4dd7ff4a03 perf stat: Add print_aggr_cgroup() for --for-each-cgroup and --topdown 
Normally, --for-each-cgroup only works with AGGR_GLOBAL.  However
the --topdown on some cpu (e.g. Intel Skylake) converts it to the
AGGR_CORE internally.

To support those machines, add print_aggr_cgroup and handle the events
like in print_cgroup_events().

  $ perf stat -a --for-each-cgroup system.slice,user.slice --topdown sleep 1
  nmi_watchdog enabled with topdown. May give wrong results.
  Disable with echo 0 > /proc/sys/kernel/nmi_watchdog
