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.
1 // Test corner cases of for-of iteration over Arrays.
2 // The current spidermonky JSOP_SPREAD implementation for function calls
3 // with '...rest' arguments uses a ForOfIterator to extract values from
4 // the array, so we use that mechanism to test ForOfIterator here.
7 // Test the properties and prototype of a generator object.
