RFR: 8155571: [JVMCI] split jdk.vm.ci module into jdk.vm.ci and jdk.vm.ci.hotspot

[Doug Simon]

In light of the Services.exportJVMCITo method being proposed in http://cr.openjdk.java.net/~dnsimon/8155023, how do you want to handle security checks and dynamically exporting packages in the jdk.vm.ci.hotspot module to JVMCI client modules?
