sparc.c (function_arg_record_value_1): Skip fields with zero length. 

* config/sparc/sparc.c (function_arg_record_value_1): Skip
	fields with zero length.
	(function_arg_record_value_2): Likewise.
	(function_arg_record_value_3): Use smallest_mode_for_size
	instead of mode_for_size.
	(function_arg_union_value): Return naked register for unions
	with zero length.
