Backport 2ad2237507c5b5f9047b8d94d2f4997327eae852 from V8. Original commit message: Fix Unhandled ReferenceError in debug-debugger.js This fixes following exception in Sky on attempt to set a breakpoint "Unhandled: Uncaught ReferenceError: break_point is not defined" I think this happens in Sky but not in Chrome because Sky scripts are executed in strict mode.
