Maybe Igor Veresov or someone else on hotspot-compiler-dev that is 
familiar with the process for pulling Graal compiler changes from 
upstream could comment in case there is coordination needed. It's just a 
move/rename so shouldn't be too disruptive.

There are several projects in OpenJDK with additional instrinics and 
they'll just need to switch over when they pull the change from the main 
repo, shouldn't be an issue.

I did comment on the update to java.base's module-info.java as I don't 
expect that jdk.internal needs to be exported to jdk.jfr with the 
change. Once @PreviewFeature moves to java.lang.annotation then that 
package will be likely be "empty" so won't be exported to anyone.
