Summary: Clean up and examine uses of classes_do for the SystemDictionary

See bug comments for more details.  I wanted to clean this up while 
examining the idea of having system dictionary information added per 
ClassLoaderData, rather than a global table.

Tested with java.lang.instrument, sun.com.jdi, tonga colocated (closed) 
tests, and JPRT, because of difference in which classes_do is called for 
heap dumping.

Note, will update copyrights on commit.
