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.

     1 // Test that we can save stacks which have generator frames.
     3 const { value: frame } = (function iife1() {
     4   return (function* generator() {
     5     yield (function iife2() {
     6       return saveStack();
     7     }());
     8   }()).next();
     9 }());
    11 assertEq(frame.functionDisplayName, "iife2");
    12 assertEq(frame.parent.functionDisplayName, "generator");
    13 assertEq(frame.parent.parent.functionDisplayName, "iife1");
    14 assertEq(frame.parent.parent.parent.functionDisplayName, null);
    15 assertEq(frame.parent.parent.parent.parent, null);
