)As a heuristic, when we see an impl, if we see that the 'self-type' is a type defined in the same module as the impl, we can omit including the path to the impl itself. This function tries to find a "characteristic def-id" for a type. It's just a heuristic so it makes some questionable decisions and we may want to adjust it later.
