Summary: remove unused code that is changing in Hotspot for hidden

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 ???
Actually I had a look at that too because, of course, I was trying to
remove more. I think there is a caller for that:
utilities/soql/sa.js:
sa.sysDict["allEntriesDo(sun.jvm.hotspot.classfile.ClassLoaderDataGraph.ClassAndLoaderVisitor)"](visitor);
But I don't know what the java script interface to SA is. So I thought
I'd leave it for now. It might actually be useful theoretically.
Thanks,
