Subject[PATCH 2/2] perf tools: Add a general option to enable raw sample records
Date
While we can enable the perf sample records per tracepoint counter,
we may also want to enable this option for every tracepoint
counters to open, so that we don't need to add a :record flag
for all of them.

Add the -R, --raw-samples options for this purpose.
