[PATCH 0/3] [ARC] Finish implementing Extended Instruction Set for NPS-400

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

This set of patches implements the remainder of the NPS-400 Extended
Instruction Set. There are no further instructions from the Extended
Instruction Set to implement, but the Accelerator Instruction Set for the
NPS-400 is unimplemented and will follow in future.

The first two patches implement arithmetic/logic instructions and Deep
Packet Inspection (DPI) instructions respectively; the third patch implements
the ldbit instruction. ldbit is also a DPI instruction, but I have
broken it out into a separate patch because its encoding overloads the
ld instruction's encoding, but differs from the standard ld instruction
by setting ZZ=11.

All patches have been tested and pass `make check` with the arc-elf and
arceb-elf targets - there are no regressions.

Graham Markall (3):
  [ARC] Add arithmetic and logic instructions for nps
  [ARC] Add deep packet inspection instructions for nps
  [ARC] Add ldbit for nps
