Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

 var s;

 function f(i) {

     if (i > 4) /* side exit when arr[i] changes from bool to undefined (via a hole) */

         assertEq(s, undefined);

     else

         assertEq(s, false);

     return 1;

 }

 /* trailing 'true' ensures array has capacity >= 10 */

 var arr = [ false, false, false, false, false, , , , , , true ];

 for (var i = 0; i < 10; ++i) {

     (s = arr[i]) + f(i);
