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> llvm-svn: 154187 2012-04-07 02:12:22 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify -Wno-objc-root-class %s`
