Options

ia64-protos.h: Remove the prototype for ia64_setup_incoming_varargs and ia64_return_in_memory. 

	* config/ia64/ia64-protos.h: Remove the prototype for
	ia64_setup_incoming_varargs and ia64_return_in_memory.
	* config/ia64/ia64.c (TARGET_STRUCT_VALUE_RTX): New.
	(TARGET_RETURN_IN_MEMORY): Likewise.
	(TARGET_SETUP_INCOMING_VARARGS): Likewise.
	(TARGET_STRICT_ARGUMENT_NAMING): Likewise.
	(ia64_setup_incoming_varargs): Adjust the arguments to meet
	the requirement of TARGET_SETUP_INCOMING_VARARGS.
	(ia64_return_in_memory): Make it static.  Change the return
	type to bool from int.  Add an argument.
	(ia64_struct_value_rtx): New.
	* config/ia64/ia64.h: Remove commented-out definitions of
	PROMOTE_FUNCTION_ARGS, PROMOTE_FUNCTION_RETURN, and
	PROMOTE_PROTOTYPES.
