Recently it has been shown that the pmu-events tests do not always catch broken uncore PMU alias support.
The main problem is that the alias matching only tests uncore PMUs which are present in the host system, so pretty useless.
This series improves that by using fake uncore PMUs, and verifying aliases generated for those PMUs match known expected values.
This means that even if one arch does not have PMUs which support some special aliasing, like multiple tokens, we can still have a fake uncore PMU test on that arch.
Support is also added to test system PMUs alias matching.
Based on 5.14-rc1 + "perf pmu: Fix alias matching".
