[PATCHv3 0/7] Add initial arc nps400 support

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

Here's a rewrite that removes the need to use the vendor string in
order change the behaviour of binutils[1].

I didn't set out to expand my 2 patch series into a 7 patch series in
order to prove that avoiding the vendor string resulted in a bunch of
extra code :) though I can understand if it looks that way.

Patch 1 is a bug fix for a new big-endian arc regression that has
crept in.

Patch 2 was patch 1 in the previous series.

Patch 3 and 4 are clean up of the constants used to setup the elf
header flags.  I hadn't looked at these too closely before, but now I
needed to add a new one I though this code could be simplified.

Patch 5 adds the new nps400 cpu type, this is the code that replaces
the use of the vendor string in the old patch 2 from my previous
iteration of this series.  I have now split this out into its own
patch as there's more of it.

Patch 6 is a new patch that modifies the way that the CLASS attribute
of arc flag operands are used.  This makes the final patch smaller
than it was previously.

Patch 7 is the new instruction part of what used to be patch 2 in the
previous iteration of this series.  I've now included a few more
instructions, so there's a few more operands.  However, thanks to
patch 6 there's actually less insert/extract code than before.

Is this OK?

Thanks,
Andrew

[1] I still don't understand why that's a bad thing though....
