* avr-tdep.c (avr_return_value): New function.

	(avr_gdbarch_init): Call set_gdbarch_return_value instead of
	set_gdbarch_extract_return_value.

	* fvr-tdep.c (frv_return_value): New function.
	(frv_gdbarch_init): Call set_gdbarch_return_value instead of
	set_gdbarch_extract_return_value, set_gdbarch_store_return_value,
	and set_gdbarch_deprecated_use_struct_convention.

	* ia64-tdep.c (ia64_use_struct_convention): Make static.
	Add check for structure, union, or array types.
	(ia64_extract_return_value): Make static.
	(ia64_store_return_value): Make static.  Support multi-word values.
	(ia64_return_value): New function.
	(ia64_gdbarch_init): Call set_gdbarch_return_value instead of
	set_gdbarch_extract_return_value, set_gdbarch_store_return_value,
	and set_gdbarch_deprecated_use_struct_convention.
