We should probably add this information as a comment to  
getMemberDecl().  Right now the documentation for MemberExpr is fairly  
spartan.  Better yet, it would be nice if getMemberDecl() returned a  
"variant" that was either CXXMethodDecl* or FieldDecl*, making this  
explicit in the type system.
