[PATCH] perf script: Add script orientation output support for monitored events

From: Wind Yu
Date: Mon Aug 28 2017 - 05:34:17 EST

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.
