[ms-cxxabi] Move MS inheritance model calculation into MemberPointerType
Summary:
This makes it possible to share code between lib/AST/MicrosoftCXXABI.cpp
and lib/CodeGen/MicrosoftCXXABI.cpp. No functionality change.
Also adds comments about the layout of the member pointer structs as I
currently understand them.
