Description
This will change the side effect logic used for
Object.freezeto be similar to the logic we currently use forObject.defineProperty: If the argument or return value is used, it is included in the bundle, otherwise it is removed. Also, we assume that the argument is deoptimized, i.e. all properties are treated as "unknown" after being passed to that function.
