Description
The annotations j.l.invoke.{ForceInline, DontInline, Stable} are currently package private but could have use outside that package if used carefully and sparingly. For example:

1) Methods on Atomic*FieldUpdater classes may benefit from @ForceInline, as would array support methods of JDK-8136924 to preserve existing inlining characteristics.
2) Reference.reachabilityFence (JDK-8133348) could be annotated with @DontInline rather than explicitly making the method signature known to the VM.
3) The alias jdk.vm.ci.hotspot.Stable could potentially be removed.
