I think we've resolved controversy about global static CHR cache (by having no global static CHR cache ;) and turned all performance issues into minor improvements. A new `ClassfileBenchmark` has been added for more precise future continuous performance monitoring.

This PR is now waiting for review to unblock all follow-up conversion work.

Thank you,
