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.

3 var g = newGlobal()
4 var dbg = Debugger(g);
5 var hits = 0;
6 g.h = function () {
7 var frame = dbg.getNewestFrame();
8 var fn = frame.eval("j").return;
9 assertEq(fn.environment instanceof Debugger.Environment, true);
10 var closure = frame.eval("f").return;
11 assertEq(closure.environment instanceof Debugger.Environment, true);
