[classlib][pack200] Removed unnecessary sort code
-------------------------------------------------

                 Key: HARMONY-5677
                 URL: https://issues.apache.org/jira/browse/HARMONY-5677
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
         Environment: All Pack200
            Reporter: Andrew Cornwall


The class pool code went through a number of sorts in order to approximate (not very well)
the sort order of the Sun pack200 code. Unless the two are identical, this isn't necessary,
and just bloats the code as well as slows it down. 

This patch (and it's a big one) removes the unnecessary sorting. It deletes the class ClassPoolSet
and a number of methods under the ClassFileEntry hierarchy. In fact, these changes may make
it easier to get identical sorting, although that's not what this patch does.

The patch improves performance by about another 25%.
