Introduce a new option to print trace output to files named by the
monitored events and update perf-script documentation accordingly.
Shown below is output of perf script command with the newly introduced
option.
$perf record -e cycles -e context-switches -ag -- sleep 10
$perf script -O
$ls /
cycles.stacks context-switches.stacks
Without the orientation option, drawing flamegraphs for different events
is really hard. You can only monitor one event at a time for perf record.
Using this option, we can get the trace output files named by the monitored
events, and could draw flamegraphs according to the event's name.
