[PATCHv2 0/7] ARC: Add support for nps400 variant

[Andrew Burgess <andrew dot burgess at embecosm dot com>]

This new iteration of the previous version is largely the same except
that I now no longer use configure time options to build in support
for nps400.  Instead support controlled with a -mcpu=nps400 command
line switch.  This change was made to mirror a similar change that was
requested when I pushed nps400 support upstream into binutils.

Most of the instructions added in this series are now in mainline
binutils, there are a few outstanding (<10) which I will return too
after this patch, but if anyone is super keen then there's a version
of binutils with full nps400 support on github:
     https://github.com/EZchip/binutils

However, all of the nps400 specific tests are compile only, so a
binutils with full nps400 support should not be required in order to
test these changes.

Thanks,
Andrew
