perf tools: Add a per tracepoint counter attribute to get raw sample
Add a new flag field while opening a tracepoint perf counter:
-e tracepoint_subsystem:tracepoint_name:flags
This is intended to be generic although for now it only supports the
r[e[c[o[r[d]]]]] flag:
./perf record -e workqueue:workqueue_insertion:record
./perf record -e workqueue:workqueue_insertion:r
will have the same effect: enabling the raw samples record for
the given tracepoint counter.
In the future, we may want to support further flags, separated
by commas.
