hi,
adding the possibility to display stat data per thread.
Allowing following commands and output:

$ perf stat -e cycles,instructions --per-task -p 12451,16173
^C
Performance counter stats for process id '12451,16173':

TASK-12451 77,784 cycles
TASK-16173 64,809 cycles
TASK-12451 14,432 instructions
TASK-16173 14,452 instructions

3.854957122 seconds time elapsed

Also woks under interval mode:

$ ./perf stat -e cycles,instructions --per-task -p 16431,16173 -I 1000
# time task counts unit events
