Instead of adding a method for WillBeHeapVector<RefPtrWillBeMember>, you should
add a method for HeapVector<Member>. (I wonder why this CL compiles when the
OILPAN flag is disabled, since we will end up having two identical methods for
Vector<RefPtr> when the OILPAN flag is disabled.)

The point is that we need methods for both Vector<RefPtr> (which we already
have) and HeapVector<Member> (which we need in this CL).

If I prepare two versions of toRefPtrNativeArray() I get the error:
error: call to 'toRefPtrNativeArray' is ambiguous

Ditto. You can add a method for HeapVector<Member>.
