ASTRecordLayout - This class contains layout information for one RecordDecl, which is a struct/union/class. The decl represented must be a definition, not a forward declaration. This class is also used to contain layout information for one ObjCInterfaceDecl. FIXME - Find appropriate name. These objects are managed by ASTContext.

hasVFPtr - Does this class have a virtual function table pointer that can be extended by a derived class? This is synonymous with this class having a VFPtr at offset zero.

inline |
hasOwnVBPtr - Does this class provide its own virtual-base table pointer, rather than inheriting one from a primary base class?
This implies that the ABI has no primary base class, meaning that it has no base classes that are suitable under the conditions of the ABI.
