Per https://www.w3.org/Bugs/Public/show_bug.cgi?id=16606, MutationObserver should expose a takeRecords() call which synchronously retrieves & clears any pending mutation records. If none are pending, it should return an empty array. It should not do anything else (in particular, it should not clear transient observers).

Anne has committed to updating the spec by end of week.
