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.
