        Rewrite of 64-bit Darwin structure-by-value pass/return.
        * config/rs6000/rs6000.h (CUMULATIVE_ARGS): New fields
        intoffset, use_stack, named.
        * config/rs6000/rs6000.c (rs6000_darwin64_function_arg):  Remove.
        (rs6000_darwin64_record_arg_advance_flush):  New.
        (rs6000_darwin64_record_arg_advance_recurse): New.
        (rs6000_darwin64_record_arg_flush):  New.
        (rs6000_darwin64_record_arg_recurse):  New.
        (rs6000_darwin64_record_arg):  New.
        (rs6000_return_in_memory):  Remove AGGREGATE_TYPE_P check.
        (function_arg_boundary):  Handle 128-bit aligned structs.
        (function_arg_advance):  Rewrite darwin64 struct handling.
        (function_arg):  Call rs6000_darwin64_record_arg.
        (function_arg_partial_nregs):  Handle darwin64 structs.
        (rs6000_darwin64_function_value):  Remove.
        (rs6000_function_value):  Call rs6000_darwin64_record_arg.
