Bug Description
Enable the Intel instruction trace (itrace), evaluate synthesizing perf events and samples from auxtrace buffe for s390x.
The auxtrace buffer contains the CPU-MF sampling data blocks that contains basic- and diagnostic sampling data entries. Similar to the cpum_sf PMU, parse the basic-sampling data entries and synthesize perf events/samples for each entry. This can be solely done in the perf tool.

Since target for 19.04 is kernel 4.20+ I'm leaving that unassigned - just monitoring...
