RFR: JDK-8289524: Add JFR JIT restart event [v5]

Fri Jul 15 14:21:06 UTC 2022

> The JIT compiler restarts (see restart_compiler in NMethodSweeper::sweep_code_cache) would be a helpful addition to the JFR events. Currently we log the JIT stop operations in JFR (EventCodeCacheFull) but no restart.

Matthias Baesken has updated the pull request incrementally with one additional commit since the last revision:

  add test for JitRestart
