If we have a property access of the form this.x, where the access site sees the global object, we can specialize the IC stub so that it performs a map check without first performing a heap object check. Ensure that we do not get in JS code with a non-JSObject this value by deoptimizing at Function.prototype.apply if the first argument is not a JSObject.
