Graham Markall 28215275a6 [ARC] Add ldbit for nps
This commit adds the ldbit instruction for the NPS-400. The ldbit
instruction uses the same encoding as the ld instruction, but sets
the ZZ field to 11 (which is a reserved setting), and sets the AA
field to 1 or 2 for the x2 and x4 flags respectively.

Andrew Burgess 4b0c052e45 arc/nps400 : New cmem instructions and associated relocation
Add support for arc/nps400 cmem instructions, these load and store
instructions are hard-wired to access "0x57f00000 + 16-bit-offset".

Supporting this relocation required some additions to the arc relocation
handling in the bfd library, as well as the standard changes required to
add a new relocation type.

There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.
