Same comment here as I commented on for StoreToSuper. Can we make this one
runtime function that takes a Smi for StrictMode? Maybe there is a reason to
prefer two runtime functions here and if so I would like to know what it is.

Less parameter passing on the stack => smaller generated code size + slightly
faster call.
