[PATCH 4/4] [ARC]: Add -mcpu=nps400 command line option

[Graham Markall <graham dot markall at embecosm dot com>]

From: Andrew Burgess <andrew.burgess@embecosm.com>

The NPS400 is the name of an ARC700 variant with a specific extension
set.  This commit adds the command line option -mcpu=nps400 which can be
used as an alternative to '-mcpu=arc700 -mnps400'.

gas/ChangeLog:

	* config/tc-arc.c (cpu_types): Add entry for nps400 as arc700 plus
	nps400 extension set.
        * testsuite/gas/arc/nps-400-0.d: Test using NPS-400 using -mcpu=nps400
        as an alternative to -mcpu=arc700 -mnps400.
