I tend to agree with Fariborz... we're pretty careful about handling  
all of the language semantics as part of AST construction, so that  
CodeGen does not need to interpret language standards. It would be  
better to have Sema create an implicit ReturnStmt at the end of main 
(), adding an Implicit bit to ReturnStmt so that clients can determine  
whether the return was implicit.
