8313c523b3 Optimize Map/Set.prototype.forEach 
Instead of using an iterator result object and an entries array
(for Map) we introduce a new runtime function that uses an array
as an out param.

On the Map ForEach perf test this leads to a 2.5x performance
improvement. On the overall Map and Set tests this leads to a 18%
and 13% improvement respectively.

3247a71c78 Do not unnecessarily expose execution state in debug event data. 
When we fire a debug event, we create duplicate execution state objects,
one as argument for the debug event listener, one as property on the
debug event data object. The latter is never used by chrome.

Avoid right shifts by zero bits: On ARM it actually means shifting by
32 bits (correctness issue) and on other platforms they are useless
(performance issue). This is fix for the fix in r20544.

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.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

70c3a714a1 ES6 Map/Set iterators/forEach improvements 
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.

When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.

With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

35b8b0b27a Move microtask queueing logic from JavaScript to C++ 
This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).

The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().
