Review Request: JDK-8157986: Runtime support for javac to determine arguments to the runtime environment

[Mandy Chung]

This patch allows jdk.compiler to get the runtime arguments without pulling in java.management (that requires java.rmi).  We should look into use cases further in the future and determine whether a public API should be provided.
