looks good to me

the PR looks good to me. You have mentioned that further refactorings could be done later on, I agree but you are already removing a lot of code, although that could have been forced to make some tests pass. I would recommend removing some support for 7 at `com.sun.tools.javac.comp.Infer` particularly the one guarded by `allowGraphInference`. I can also help with that later on if you prefer. If so please assign a follow-up for this issue to myself
