  [JSC] Fix reportExtraMemoryAllocated uses when resolving rope strings

Reviewed by Yusuke Suzuki.

Heap::reportExtraMemoryAllocated may trigger JSRopeString::resolveRope.
If this API needs to be used when resolving a rope string, then we should
make sure to call this API after the rope string is completely resolved.
