Your approach is not wrong, but I think that is better for consistency 
if you implement typeid in a similar way as sizeof/alignof is implemented.
sizeof for type calls Action.ActOnSizeOfAlignOfTypeExpr (creating a 
SizeOfAlignOfTypeExpr node), while sizeof for expression calls 
Action.ActOnUnaryOp (creating a UnaryOperator expression node).
