0c8cd46302 ARM64: Restructure the L1 deopt jump table.
This restructures the L1 deopt jump table so that the base address of
the L2 table is only loaded once. This significantly reduces the size of
the generated code because only one big immediate needs to be loaded.

The total size of all L1 deopt tables generated during Octane is almost
halved in size, from about 1105kB to 584kB.

60a71d8a8c Remove PROHIBITS_OVERWRITING as it is subsumed by non-configurable properties.
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.

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).
