[Gao, Yunzhong]

The rest of the patch looks good by me. You might want to check with John if he has any comments.

  A coding style question:

  It seems that CGRecordLowering is exposing a lot of its member fields and functions. I wonder whether it makes sense to make some of these member fields private. For example, it seems
    std::vector<MemberInfo> Members
  does not need to be referenced by outside classes, and could be made private (and hence the definition of MemberInfo). I did not check all the "Input Memoization fields", but I suspect some of them do not need to be exposed either. And some of the member functions as well, such as,
    void lowerUnion();
  and some other functions used by lower(), probably can be hidden from outside classes as well.

  I think this is minor point since CGRecordLowering is only defined and used in this file, and I am not entirely sure about LLVM's coding style on access control. What do the other reviewers think?

Adding private: around everything except the entry points is probably a good idea, but I don't think it matters too much.  All that stuff is TU local anyway.
