perf/amd/ibs: Enable streaming store filter

Browse source

IBS OP on future hardware supports recording samples only for instructions
that does streaming store. Like the existing IBS filters, samples pointing
to instruction which does not cause streaming store are discarded and IBS
restarts internally.

Example:

  $ perf record -e ibs_op/strmst=1/ -- <workload>
