James Hilliard 9679d839f8 target/mips: decode Octeon CRC and GFM COP2 selectors 
Add explicit decodetree entries and translator bindings for the Octeon
CRC and GFM COP2 operation selectors. Unlike simple register moves,
these selectors update CRC or Galois-field state and therefore remain
per-operation helper calls.

Keep CRC/GFM decode next to the helpers that implement these side
effects while avoiding a monolithic selector-dispatch helper.
