The following series includes emulation of the platform-specific MIPS extension
for Cavium Octeon CPUS:
- basic Octeon vCPU model
- custom instruction decoder for Octeon
- implementation of arithmetic and logic instructions

v2 changes:
 - simplified instruction decoding and translation (suggested by Richard Henderson)
