      Description

      There are a few ideas
      [1] Move more fields from Method -> ConstMethod
           See JDK-8145234 and JDK-8145221
      [2] Split InstanceKlass into a read-write part and a read-only part.
      [3] Do something about ConstantPool.

      We should investigate the possibilities and see if we can do some of the work in JDK9 vs follow-on releases.
