Do we have a plan for a better way to do this?

Even though unittest.dart is included, it isn't included in the dill file unless
we actually use it. By reading this field we actually use the file, and it is
thus included in the file.
If it isn't included we cannot set breakpoints in unittest.dart.

I don't know. It seems somewhat artificial to me to want to set a breakpoint in
an unused library, so I'm pretty okay with this...
