RFR: JDK-8290839: jdk/jfr/event/compiler/TestJitRestart.java failed with "RuntimeException: No JIT restart event found: expected true, was false" [v2]

[Matthias Baesken]

> In seldom cases the TestJitRestart.java JFR test failed because no Jitrestart event was seen in the test.
> Dean Long suggested to change the test a bit "How about changing the test to look at CodeCacheFull, compilation, and JitRestart events. It can test that no compilation events happen after CodeCacheFull unless a JitRestart comes first. So it would be testing the order of events and not absolute counts."
> 
> So I adjusted the test (still succeeds after a JitRestart is seen, but in case it is not seen only fails in case of Compilation events after CodeCacheFull).
