The patch below hookizes FUNCTION_ARG and related macros for the avr
backend.  Nothing special here.

Tested by inspection with cross to avr-elf.  I plan to commit this
under the obvious rule after waiting a week for comments/approval.

	* config/avr/avr-protos.h (function_arg): Delete.
	(function_arg_advance): Delete.
	* config/avr/avr.h (FUNCTION_ARG, FUNCTION_ARG_ADVANCE): Delete.
	* config/avr/avr.c (function_arg): Rename to...
	(avr_function_arg): ...this.  Make static.  Take a const_tree and
	a bool.
	(function_arg_advance):	Rename to...
	(avr_function_arg_advance): ...this.  Make static.  Take a
	const_tree and a bool.
	(TARGET_FUNCTION_ARG, TARGET_FUNCTION_ARG_ADVANCE): Define.

Looks obvious to me. Please commit. And thanks for doing this. :-)
