Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.

 // Arrow functions can have primitive |this| values.

 Number.prototype.foo = function() {

     "use strict";

     return () => this;

 }

 for (var i=0; i<5; i++) {

     var n = i.foo()();

     assertEq(typeof n, "number");

     assertEq(n, i);

 }
