We should investigate why this bug is still referenced in RFR. We already discussed it:
https://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2019-March/033130.html

We also discussed indentation change in make/test/JtregGraalUnit.gmk
Why the change showed up again?

Otherwise changes looks good.

Doug, it is good to have only one Graal class to access Unsafe class - GraalUnsafeAccess.java.
But we should not use sun.misc.Unsafe in JDK 13 - we should have version for JDK9+ which use 
jdk.internal.misc.Unsafe. It is for an other update.

Thanks,
Vladimir
