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 works on ancestors of frame.environment.

 var g = newGlobal();

 var dbg = Debugger(g);

 var log = '';

 dbg.onDebuggerStatement = function (frame) {

     for (var env = frame.environment; env; env = env.parent) {

         if (env.find("x") === env)

             log += env.getVariable("x");

     }

 };

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

 assertEq(log, "321");
