Okay, looks good.  (The thought crossed my mind that we might want to
put this on ASTContext rather than Expr, but it doesn't really
matter.)

Something I thought of just now: how do we want to represent a pointer
expression that's an offset from the null pointer?  Using a null Expr*
+ offset?  Or as an APSInt?  I'm thinking a null Expr*+offset is more
consistent/intuitive, but I thought I'd mention it in case someone can
think of a case where an APSInt representation would be more
useful/easier to deal with.
