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.

- Move HType to it's own file.
- Add HType::HeapObject and some other useful types.
- Get rid of the broken and useless HType::NonPrimitive.
- Introduce HType::FromType() to convert from HeapType to HType.
- Also add unit tests for HType.
- Fix types in Crankshaft.

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).

7ac892c8bd Establish distributivity for type union & intersection 
This requires introducing proper bounds on all leaf types, so that intersection between bitsets and these types can be accurately represented. Extending a union also becomes more involved.

(On the upside, the modified union/intersect algorithm would now allow support for proper variance for function types.)

Not sure if it is worth landing this. Distributivity isn't really a crucial property for our use cases. It seems fine if intersection is slightly lossy.
