* i386.c (struct machine_function): Add new fields for PIC stuff.
        (save_386_machine_status): Fix argument to xmalloc.  Save pic_label_rtx
        and pic_label_name.
        (restore_386_machine_status): Corresponding changes.
        (clear_386_stack_locals): Also clear pic_label_rtx and pic_label_name.
