        * common/config/arc/arc-common.c (arc_handle_option): Add NPS400
        support, setup defaults.
        * config/arc/arc-opts.h (enum processor_type): Add NPS400.
        * config/arc/arc.c (arc_init): Add NPS400 support.
        * config/arc/arc.h (CPP_SPEC): Add NPS400 defines.
        (TARGET_ARC700): NPS400 is also an ARC700.
        * config/arc/arc.opt: Add NPS400 options to -mcpu=.
