Currently, the IR framework uses -XX:+PrintCompilation in the test VM to check the compilation status of the @Test annotated methods (set in getPrintFlags() in FlagVM.java).

This can now be improved by using the new PrintCompilation compiler directive added by JDK-8255746 to only dump the compilation information of the @Test annotated methods.

Additionally, we could probably improve the HotSpotPidFileParser class as we do not need to check anymore if a PrintCompilation message belongs to a @Test annotated method or not, making the parser more efficient and probably easier.
