26044 redundant MEM attr setting.
26045 (expand_one_stack_var_1): Handle anonymous SSA_NAMEs. Renamed

26058 SA.partition_to_pseudo from partition leaders and cleared
26059 DECL_RTL for multi-location variables, and that which used to
26060 rename vars and set attrs, with one that clears DECL_RTL and
26061 checks that PARMs and RESULTs default_defs match DECL_RTL.
