RFR: 8252329: runtime/LoadClass/TestResize.java timed out [v3]

[Coleen Phillimore]

> This test loads 50k classes and then does PrintSystemDictionaryAtExit.  The timeout seems to be during processing the output to find the load factor of the dictionary.  I reduced the number of classes to 30K, which causes the one resize, and added the output to PrintClassLoaderDataAtExit, which is only 100 lines of output vs. 51000 lines of output.
> I also added Verbose to PrintClassLoaderDataAtExit to print all the classes, since if you really want all the classes, you should use PrintSystemDictionaryAtExit.
> Tested with tier1.
