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

> 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.

I have applied the approved versions of these patches on Graham
behalf.
