Issue Description:

Given the following sample code:

import Foundation
CharacterSet.letters.isSuperset(of: CharacterSet(charactersIn: "ab"))

I get the following runtime crash:

2016-08-09 12:01:16.993 swift[91581:18094762] Abstract class Foundation._SwiftNSCharacterSet does not implement method isSupersetOfSet:; it must be implemented in subclasses.
2016-08-09 12:01:16.994 swift[91581:18094762] -[Foundation._SwiftNSCharacterSet isSupersetOfSet:]: unrecognized selector sent to instance 0x7fbe7ad14d10
2016-08-09 12:01:17.058 swift[91581:18094762] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Foundation._SwiftNSCharacterSet isSupersetOfSet:]: unrecognized selector sent to instance 0x7fbe7ad14d10'

I've tried Xcode 8 beta 4, but I believe it should be reproducible on Swift master as well because '_SwiftNSCharacterSet' defined in 'https://github.com/apple/swift/blob/master/stdlib/public/SDK/Foundation/CharacterSet.swift' doesn't implement this method.
