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.

 // find sees that vars are hoisted out of with statements.

 var g = newGlobal();

 var dbg = Debugger(g);

 var hits = 0;

 dbg.onDebuggerStatement = function (frame) {

     assertEq(frame.environment.find("x").type, "with");

     hits++;

 };

 assertEq(g.eval("(function () {\n" +

                 "    function g() { x = 1; }\n" +

                 "    with ({x: 2}) {\n" +
