4246: Validate uses of self and super r=matklad a=djrenren This change follows on the validation of the `crate` keyword in paths. It verifies the following things: `super`: - May only be preceded by other `super` segments - If in a `UseItem` then all semantically preceding paths also consist only of `super` `self` - May only be the start of a path Just a note, a couple times while working on this I found myself really wanting a Visitor of some sort so that I could traverse descendants while skipping sub-trees that are unimportant. Iterators don't really work for this, so as you can see I reached for recursion. Considering paths are generally small a fancy debounced visitor probably isn't important but figured I'd say something in case we had something like this lying around and I wasn't using it.
