new lint: `into_iter_without_iter` Closes #9736 (part 2) This implements the other lint that my earlier PR missed: given an `IntoIterator for &Type` impl, check that there exists an inherent `fn iter(&self)` method. changelog: new lint: `into_iter_without_iter` r? `@Jarcho` since you reviewed #11527 I figured it makes sense for you to review this as well?
