OK, this is actually just a cleanup patch. No functional difference between 
"before" and "after". For more flexible argument, like array type, we need
to decouple with argument name and its value printing. Is below more clear
to you?


Cleanup argument-printing functions to decouple it into name-printing and
value-printing, so that it can support more flexible argument expression,
like array type.
