There's a fair amount of complexity in member pointers.
- Can I mangle in a null data memptr here?
- The null representation is different between standard layout records (-1) and other records (0).
- Can I mangle a field from a base class that is not at offset 0?

All this is currently handled in CodeGen/MicrosoftCXXABI.cpp, which this AST code can't depend on.  We could raise some parts of it up into the AST CXXABI if needed.
