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.
