This commit does a few things: 1. It uses SwitchEnumBuilder so we are not re-inventing any wheels. 2. Instead of hacking around not putting in a destroy for .None on the fail pass, just *do the right thing* and recognize that we have a binary case enum and in such a case, just emit code for the other case rather than use a default case (meaning no cleanup on .none). rdar://31145255
