[9] RFR[L] 8174879: Rename jdk.vm.ci to jdk.internal.vm.ci

[Vladimir Kozlov]

https://bugs.openjdk.java.net/browse/JDK-8174879

jdk.vm.ci and jdk.vm.compiler are purely JVM internal modules that is only of interest to VM developers (and researchers), not general Java developers. It'd be appropriate for it to be an internal 
module and not to export any API.

Rename jdk.vm.ci and jdk.vm.compiler modules to jdk.internal.vm.ci and jdk.internal.vm.compiler. No packages renaming.
Exports jdk.vm.ci.services only to jdk.internal.vm.compiler.

jdk: http://cr.openjdk.java.net/~kvn/8174879/webrev.jdk/
hotspot: http://cr.openjdk.java.net/~kvn/8174879/webrev.hs/

Tested with RBT.

Thanks,
