2022-01-11	perf test: Enable system wide for metricgroups test	Ian Rogers
	Uncore events as group leaders fail in per-thread mode causing exit errors. Enable system-wide for metricgroup testing. This fixes the HPC metric group when tested on skylakex.

2021-09-28	perf test: Workload test of metric and metricgroups	Ian Rogers
	Test every metric and metricgroup with 'true' as a workload. For metrics, check that we see the metric printed or get unsupported. If the 'true' workload executes too quickly retry with 'perf bench internals synthesize'. v3. Fix test condition (thanks to Paul A. Clarke <pc@us.ibm.com>). Add a fallback case of a larger workload so that we don't ignore "<not counted>". v2. Switched the workload to something faster.
