Improve write barriers in optimized code.
...
Use a cheaper RecordWriteForMap() to update the
write barrier for maps. And skip the value check
in RecordWriteField() when we statically know that
the value is in new space (and therefore has "pointers
to here are interesting" flag set).

v8::DontDelete is set for Unforgeable properties, so just not setting PROHIBITS_OVERWRITING should be enough.
The secondary "feature" of not allowing accessors to be installed in extending objects is incorrect and confusing, given that it only applies to accessors but not to regular properties:
Object.defineProperty({__proto__:window}, "location", { value: 10 })
works where
Object.defineProperty({__proto__:window}, "location", { get: function() {} })
doesn't work.

Simplify, speed-up correct-context ObjectObserve calls
...
The original patch which ensured that Object.observe did allocations in the correct context regressed performance about 12%. This patch gets back most of that (about 11%) by simply returning the correct function which is then directly callable from JS, rather than by making the call from the runtime function. A side-effect is that their implementation is shorter.

Allow microtasks to throw exceptions and handle them gracefully
...
If the embedder calls V8::TerminateExecution while we're running microtasks, bail out
and clear any pending microtasks.
All other exceptions are simply swallowed. No current Blink or V8 microtasks throw, this
just ensures something sane happens if another embedder decides to pass a throwing
microtask (or if ours unexpectedly throw due to, e.g., stack exhaustion).

FastCloneShallowArrayStub should not be used it the length of the array is too big as it could eventually exceed the allowed size limit for manually folded allocations.
