we should do this above as well, yes? After resolve_ident_in_lexical_scope? I'm not sure

Discussed here @Manishearth and I figured that we couldn't find other ways to get resolve to trigger those use cases, so we'll fix them up later if they come up and otherwise we'll move forward w/ this.

Ok the bug that I found was that the previous changes would lint for imports like I've done what I hope is a thorough review of librustc_resolve for where 2015/2018 diverge and have added a lint to the appropriate locations (hopefully). Now re-r? @Manishearth |

This is something that was accidentally omitted from the lint entirely before, where use * is completely forbidden in 2018 and so this starts to lint about that in 2015.
Note that there's still a "bug" in the lint for "remove extern crate", I'll file a bug for that shortly

The renaming would need to be backported or the old name put into the deprecated lint list
