Enumerate a set of special purposes for function arguments that general purpose code needs to know about. Some of these argument purposes will only appear in the signature of the current function, representing things the prologue and epilogues need to know about like the link register and callee-saved registers. Get rid of the 'inreg' argument flag. Arguments can be pre-assigned to a specific register instead.
