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.

 // getVariable sees properties inherited from a with-object's prototype chain.

 var g = newGlobal();

 var dbg = Debugger(g);

 var v;

 dbg.onDebuggerStatement = function (frame) {

     v = frame.environment.getVariable("x");

 };

 g.eval("var x = 1; { let x = 2; with (Object.create({x: 3})) { debugger; } }");

 assertEq(v, 3);
