Again, fix two problems with implicit conversions: - rdar://problem/16776273, wherein conversions between nil and .None were permitted due to an implicit conversion between nil and COpaquePointer. - rdar://problem/16877526, where we needed to add new equality overloads to handle conversions between nil and .None given the supression of user conversions. (Some minor tweaks this time around for better interoperability with AnyObject.) Swift SVN r18498
