74f92f21da 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.

20eeff9ae4 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).

1102eeafe4 Reuse ZoneList memory if possible. 
Clear() is rather wasteful for ZoneLists, because it discards
all previously allocated memory, making it impossible to reuse
until the whole Zone is released. Better use Rewind(0) in this
case, which just resets the length to zero.
