Currently we only bind self if the type is callable, but we actually should do this for all callable items in a union.
This use case is probably quite niche (since adding an annotation makes a variable an instance variable, and we rarely infer unions). I found it when looking at
checkmember-related issues it was easy to handle it. I also use this opportunity to refactor and add comments toanalyze_var().
