[analyzer] Improve localizability checks for iOS / OS X.
Various improvements to the localization checker: * Adjusted copy to be consistent with diagnostic text in other Apple API checkers. * Added in ~150 UIKit / AppKit methods that require localized strings in UnlocalizedStringsChecker. * UnlocalizedStringChecker now checks for UI methods up the class hierarchy and UI methods that conform for a certain Objective-C protocol. * Added in alpha version of PluralMisuseChecker and some regression tests. False positives are still not ideal. A patch by Kulpreet Chilana! Differential Revision: http://reviews.llvm.org/D12417 llvm-svn: 248350
