ad window-custom-prototype) This is expected bahavior, consistent with
SpiderMonkey. The test expectation is broken. Assigning 'null' to
'__proto__' makes the accessor installed on Object.prototype disappear.

ad JSON-parse) The result of JSON.parse() doesn't match the result we
get when evaluating the same string through eval() as V8 still has
special handling of the __proto__ property for object literals.

ad cyclic-prototypes) Test fully matches the WebKit expectation now and
no longer fails. However the exception message has a slightly different
format and hence causes a text diff.
