[vw7.3.1 and later][bug?][refactor] -- when push an instance variable down, it goes to the end of the list of iv's in the subclass rather than the beginning...

If you have a class Foo with IV foo and a child class Child with an IV
child, and you ask to push down the IV foo, then you get

        Child
                Iv:  child foo

rathe than

        Child
                iv:  foo child

So, exisiting instances of Child now have the foo value in child and the
child value in foo.
