Issue Description:

NSString allows nil,

public func getLineStart(_ startPtr: UnsafeMutablePointer<Int>?, end lineEndPtr: UnsafeMutablePointer<Int>?, contentsEnd contentsEndPtr: UnsafeMutablePointer<Int>?, for range: NSRange)

but String does not:

public func getLineStart(_ start: UnsafeMutablePointer<Index>, end: UnsafeMutablePointer<Index>, contentsEnd: UnsafeMutablePointer<Index>, for range: Range<Index>)

I think String is not right.

This difference is still existent in the Xcode 9.4.1 toolchain.
