Subject: [PATCH v2 7/9] perf pmu-events: Introduce pmu_metrics_table
Add a metrics table that is just a cast from pmu_events_table. This
changes the APIs so that event and metric usage of the underlying
table is different. Later changes will separate the tables.
This introduction fixes a NO_JEVENTS=1 regression on:
68: Parse and process metrics : Ok
70: Event expansion for cgroups : Ok
caused by the necessary test metrics not being found.
