to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

We haven't supported compiling ObjC1 for a long time (and never will again), so
there isn't any reason to keep these separate. This patch replaces
LangOpts::ObjC1 and LangOpts::ObjC2 with LangOpts::ObjC.

Summary: I did not put lang opt check in AvoidSpinlockCheck since OSSpinLock is not objc specific. We won't want to skip it when analyzing some C++ target used by other ObjC sources.

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`
