perf stat: Resort '--per-thread' result
There are many threads reported if we enable '--per-thread' globally. 1. Most of the threads are not counted or counting value 0. This patch removes these threads. 2. We also resort the threads in display according to the counting value. It's useful for user to see the hottest threads easily. For example, the new results would be: root@skl:/tmp# perf stat --per-thread ^C Performance counter stats for 'system wide': perf-24165 4.302433 cpu-clock (msec) # 0.001 CPUs utilized vmstat-23127 1.562215 cpu-clock (msec) #
