I'm not sure how to identify unused code in the SA given that it exposes 
a Java API for querying the JVM internals. You say 
getisUnsafeAnonymous() is unused because nothing in the SA calls it. But 
the same would seem to be true for other parts of the CLD API - for example

- ClassLoaderData::dictionary() is called from
   - ClassLoaderData::allEntriesDo, is called from
     - ClassLoaderDataGraph::allEntriesDo, is called from
       - nowhere ???
