There's no big value on displaying counts for every event ID, which is
one per every CPU. Rather than that, displaying the whole sum for the
event.

  $ perf record -c 100000 -e cycles:u -s test
  $ perf report -T

Before:
  #  PID   TID  cycles:u  cycles:u  cycles:u  cycles:u  ... [20 more columns of 'cycles:u']
    3339  3339         0         0         0         0
    3340  3340         0         0         0         0
    3341  3341         0         0         0         0
    3342  3342         0         0         0         0

Now:
  #  PID   TID  cycles:u
    3339  3339     19678
    3340  3340     18744
    3341  3341     17335
    3342  3342     26414
