Haojian Wu	e010406e28	[clang-tidy ObjC] [3/3] New check objc-forbidden-subclassing ... Summary: This is part 3 of 3 of a series of changes to improve Objective-C linting in clang-tidy. This adds a new clang-tidy check `objc-forbidden-subclassing` which ensures clients do not create subclasses of Objective-C classes which are not designed to be subclassed. (Note that for code under your control, you should use __attribute__((objc_subclassing_restricted)) instead -- this is intended for third-party APIs which cannot be modified.) By default, the following classes (which are publicly documented as not supporting subclassing) are forbidden from subclassing: ABNewPersonViewController ABPeoplePickerNavigationController ABPersonViewController ABUnknownPersonViewController NSHashTable NSMapTable NSPointerArray NSPointerFunctions NSTimer UIActionSheet UIAlertView UIImagePickerController UITextInputMode UIWebView Clients can set a CheckOption `objc-forbidden-subclassing.ClassNames` to a semicolon-separated list of class names, which overrides this list. Test Plan: `ninja check-clang-tools` Patch by Ben Hamilton!
