Bug 171543 – [ES6] Arrow function. Issue in access to this after eval('super()') within constructor

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

Hmm, during investigation error 171274 I faced in error in binding `this` & superCall in arrow function.
```
class A extends Object {
    constructor () {
        var arrow = () => { eval('super()'); print(this.id);} 
        arrow();
    }
};

new A // ReferenceError: Cannot access uninitialized variable. But should be OK.
```
Before I was sure that we always load `this` from virtual scope in arrow function within constructor, but it is not true
