The jevent "Compat" is used for uncore PMU alias or metric definitions.
The same PMU driver has different PMU identifiers due to different hardware versions and types, but they may have some common PMU metric. Since a Compat value can only match one identifier, when adding the same metric to PMUs with different identifiers, each identifier needs to be defined once, which is not streamlined enough.
So let "Compat" support using regular expression to match multiple identifiers for uncore PMU metric.
