This avoids casting problems in case of empty_fixed_array as
FixedDoubleArray with size 0. This avoids prematurely shortcutting in
case of 0 all over the place, which in turn leads to errors.

Making the code size predictable is hard, and to make things even more
complicated, the start of a function can contain various stuff like calls to a
profiling hook, receiver adjustment or dynamic frame alignment. Instead of
tackling all these problems separately, we now simply record the offset where
patching should happen later in the Code object itself.

Callbacks that run after garbage collection might fire a context dispose
notification and hence increse the counter before we actually reach this
position.

This avoids bogus calls to Fixed*Array::cast() when FastElements-backed objects are empty (and thus backed by empty_fixed_array).

These are likely causing some of the flaky crashes in Object.observe code. I've reorganized some of the code to minimize the number of necessary calls to map() (by saving the result of map()->is_observed() in a local bool).

Also move down an unnecessarily early call to Uint32ToString when sending an element deletion notification.

Weak persistent handle callbacks might trigger nested GCs that in turn
can cause marking to be restarted. The assertion needs to hold before
firing callbacks only.

Some unit tests specifically test scavenges and forcing them to do
global GCs instead makes no sense. The GC stress builder triggers this.

The heap snapshot generator uses the UnreachableObjectsFilter which in
turn messes with marking bits. This requires incremental marking to be
turned off while the snapshot is being generated.
