RFR (XXL): JEP 243: Java-Level JVM Compiler Interface

[Christian Thalinger]

The JEP itself can be found here:

https://bugs.openjdk.java.net/browse/JDK-8062493 <https://bugs.openjdk.java.net/browse/JDK-8062493>

Here are the webrevs:

http://cr.openjdk.java.net/~kvn/JVMCI/webrev.hotspot/ <http://cr.openjdk.java.net/~kvn/JVMCI/webrev.hotspot/>

The change has already undergone a few iterations of internal review by different people of different teams.  Most comments and suggestions were handled accordingly.  Although there is one open item we agreed we will address after the integration of JEP 243 and that work is captured in RFE:

https://bugs.openjdk.java.net/browse/JDK-8134994 <https://bugs.openjdk.java.net/browse/JDK-8134994>

SQE is still working on the tests and all test tasks can be seen as sub-tasks of the JEP.

The integration will happen under the bug number:

https://bugs.openjdk.java.net/browse/JDK-8136421 <https://bugs.openjdk.java.net/browse/JDK-8136421>
