Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.

The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>
