Revert "ART: Use proxy ArtMethod's data_ to store the interface method."

Broke a few tests with:
+dalvikvm64 F 08-14 18:36:32 136697 136697 art_method-inl.h:392] Check failed: interface_method->GetDeclaringClass()->IsAssignableFrom(GetDeclaringClass()) 


This reverts commit 0888cf1821d6622fd623db31000be19b9365f81c.
