Delivery logic for Object.observe
This CL has two parts: the first is the logic itself, whereby each observer callback is assigned
a "priority" number the first time it's passed as an observer to Object.observe(), and that
priority is used to determine the order of delivery.
The second part invokes the above logic as part of the API, when the JS stack winds down to
zero.
Added several tests via the API, as the delivery logic isn't testable from a JS test
(it runs after such a test would exit).

Fix slack tracking when instance prototype changes.
This fixes a corner case when the instance prototype of a function is
changed while inobject slack tracking is still in progress. This caused
the intial map to be unrelated for functions with the same shared info
and hence the shared construct stub is no longer generic enough to work
for all those functions.

Fix disabling of code flusher while marking.
This fixes a corner case when the code flusher is disabled while
incremental marking is running. The list of candidates needs to be
evicted to prevent list fragments without a head floating around.
