JDK 12 RFR of JDK-8205615: Start of release updates for JDK 12 / JDK-8205621: Increment JDK version for JDK 12

[Paul Sandoz]

This generally looks good. Having it all consolidated helps a lot, and we are slowly chipping away at reducing this for each release.

src/jdk.compiler/share/classes/com/sun/tools/javac/jvm/ClassFile.java
—

 118         V55(55, 0),   // JDK 11: constant dynamic
 119         V56(56, 0);   // JDK 12


We can add nestmates to the list of stuff in 11
