perf tools: Allow multiple threads or processes in record, stat, top
Allow a user to collect events for multiple threads or processes
using a comma separated list.
e.g., collect data on a VM and its vhost thread:
perf top -p 21483,21485
perf stat -p 21483,21485 -ddd
perf record -p 21483,21485
or monitoring vcpu threads
perf top -t 21488,21489
perf stat -t 21488,21489 -ddd
perf record -t 21488,21489
