[PATCHv2 0/4] arc/nps: Add pipeline control instructions

[Andrew Burgess]

Second version of adding pipeline control instructions.  No
significant changes here, two clean up patches from round 1 that were
approved have been applied upstream, and this patch series rebased
onto current HEAD of master.

There's a new comment describing the layout of arc_opcodes table added
in patch #3, but everything else is unchanged.

Thanks,
Andrew
