Add ArgList::MakeArgString and make ArgList::Make* const.
 - Slightly strange, but the idea is that the ArgList data structure
   is primarily a list of arguments; we want to allow clients to still
   add argument strings to an ArgList to avoid worrying about string
   lifetimes (or unnecessary string copying).
