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.
