Nathan Hawes 15f5222bbd [CodeCompletion][Sema] Allow missing args when solving if the completion location indicates the user may intend to write them later. ...

func foo(a: Int, b: Int) {}
func foo(a: String) {}

// Int and String should both be valid, despite the missing argument for the
// first overload since the second arg may just have not been written yet.
foo(a: <complete here>

func bar(a: (Int) -> ()) {}
func bar(a: (String, Int) -> ()) {}

// $0 being of type String should be valid, rather than just Int, since $1 may
// just have not been written yet.
bar { $0.<complete here> }
