This changed to be resolved by overload resolution in Swift 4, and so can suddenly be shadowed by similarly named properties and functions that are visible at the expression's location. When in Swift 3 mode, if there is a visible declaration named "type", add the `Swift.` prefix to disambiguate in Swift 4 mode. rdar://problem/31997321
