Mike Pennisi 219bdc6f73 Promise: Add tests to disallow faulty optimization 
Add tests that assert behavior when a Promise is resolved with another
Promise whose `then` method has been overridden. Because all objects
with a `then` method are treated equivalently, the presence of a
[[PromiseState]] internal slot should have no effect on program
behavior.

These tests guard against a faulty optimization originally implemented
in V8:
