sparc.c (sparc_sr_alias_set): Don't define.

	* config/sparc/sparc.c (sparc_sr_alias_set): Don't define.
	(struct_value_alias_set): Don't define.
	(sparc_option_override): Don't set sparc_sr_alias_set and
	struct_value_alias_set.
	(save_or_restore_regs): Use gen_frame_mem rather than calling
	set_mem_alias_set.
	(sparc_struct_value_rtx): Likewise.
