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.

 // frame.arguments works for all live frames

 var g = newGlobal();

 var dbg = new Debugger(g);

 var hits = 0;

 dbg.onDebuggerStatement = function (frame) {

     for (var i = 0; i <= 4; i++) {

         assertEq(frame.arguments.length, 1);

         assertEq(frame.arguments[0], i);

         frame = frame.older;

     }

     assertEq(frame, null);

     hits++;

 };

 g.eval("function f(n) { if (n == 0) debugger; else f(n - 1); }");

 g.f(4);

 assertEq(hits, 1);
