LGTM with nits.

https://codereview.chromium.org/23708030/diff/1/src/heap-inl.h
File src/heap-inl.h (right):

https://codereview.chromium.org/23708030/diff/1/src/heap-inl.h#newcode617
src/heap-inl.h:617: if (FLAG_gc_greedy)
ISOLATE->heap()->GarbageCollectionGreedyCheck()
Wrap argument in ()

https://codereview.chromium.org/23708030/diff/1/src/heap-inl.h#newcode648
src/heap-inl.h:648:
ISOLATE->counters()->gc_last_resort_from_handles()->Increment();           \
... and we should probably wrap () around ISOLATE in this macro, too.

File src/heap.cc (right):

https://codereview.chromium.org/23708030/diff/1/src/heap.cc#newcode734
src/heap.cc:734: ASSERT(array->map() != this->fixed_cow_array_map());
Why do we need "this->"?
