Reviewers: Michael Starzinger, Description: Object.observe: prevent observed objects from using fast elements.
This is necessary because polymorphic stores generally do not perform a map check but only an instance type check, which misses out on changes in the observation status. Unfortunately, there currently is no efficient way in V8 to maintain that optimisation in the presence of Object.observe.
