This now fails because of the additional dependencies imposed by strong mode.

I'd really like to understand what changed to cause this test to fail. Those
additional dependencies caused new tasks to be run, so those tasks must be doing
something different. I think we need to get this passing.

Concretely, it's the extra input dependencies on LIBRARY_CYCLE that require a
LIBRARY_ELEMENT2 for the unit and for its import/export closure.  If I eliminate
them, this test passes.  I agree that we should fix this.  I'd like to just
filter those dependencies in the non strong mode case, but we don't seem to have
a good way to do that.  Should this test pass even given those extra
dependencies?  I don't think it should in strong mode - if class A or B had an
inferred top level field or static, then resolution of b needs to be
invalidated.  If it should still pass in regular mode (even given the extra
dependencies) then I need to understand how the invalidation logic works better
to fix it - I'll need some help with that.
