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.

 // Error().stack (ScriptFrameIter) should see through JS_SaveFrameChain.

 function gamma() {

     stack = Error().stack;

 }

 function beta() {

     evaluate("gamma()", {saveFrameChain: true});

 }

 function alpha() {

     beta();

 }

 alpha();

 assertEq(/alpha/.test(stack), true);

 assertEq(/beta/.test(stack), true);

 assertEq(/gamma/.test(stack), true);
