Log:
We now have a test case for stopping within a module in a place where the
translation unit has a interface for a class "Bar" that contains hidden ivars
in the implementation and we make sure we can see these hidden ivars. We also
test the case where we stop in translation unit that contains the 
implementation first. So the test runs two tests:

1 - run and stop where we have an interface, run to main and print and make
    sure we find the hidden ivar
2 - run and stop where we have an implementation, run to main and print and make
    sure we find the hidden ivar
