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.

 // defineProperty can add array elements, bumping length

 var g = newGlobal();

 g.a = g.Array(0, 1, 2);

 var dbg = new Debugger;

 var gw = dbg.addDebuggee(g);

 var aw = gw.getOwnPropertyDescriptor("a").value;

 aw.defineProperty(3, {configurable: true, enumerable: true, writable: true, value: 3});

 assertEq(g.a.length, 4);
