Jiri Olsa b31d660df3 perf tests: Add test to check for event times
This test creates software event 'cpu-clock' attaches it in several ways
and checks that enabled and running times match.

Committer notes:

Testing it:

  [acme@jouet linux]$ perf test -v times
  44: Test events times                                        :
  --- start ---
  test child forked, pid 27170
  attaching to spawned child, enable on exec
    OK    : ena 307328, run 307328
  attaching to current thread as enabled
    OK    : ena 7826, run 7826
  attaching to current thread as disabled
    OK    : ena 738, run 738
  attaching to CPU 0 as enabled
    SKIP  : not enough rights
  attaching to CPU 0 as enabled
    SKIP  : not enough rights
  test child finished with -2
  ---- end ----
  Test events times: Skip
  [acme@jouet linux]$

  [root@jouet ~]# perf test times
