Bug:
  https://bugs.openjdk.java.net/browse/JDK-8211228

Fix:
  http://cr.openjdk.java.net/~shade/8211228/webrev.01/

Recent addition of JFR events to G1 broke Zero build. That is because Zero builds with JFR disabled,
but G1 enabled (it is a separate question why!). It can be fixed by putting JFR_ONLY all around
JFR-specific code, or by configuring Zero to avoid building g1gc. But, since it looks like AIX is
also affected by this:
  https://bugs.openjdk.java.net/browse/JDK-8211213

...I'd prefer to protect the JFR paths.

Testing: x86_64 zero build, x86_64 server build

Thanks,
-Aleksey
