Hi,

This is my attempt of converting MIPS translation code into decodetree.

Currently only MIPS I to MIPS Release 5 arithmatic functions are converted.
Old decoding functions are perserved in codebase for now due to dependencies
from microMIPS/nanoMIPS translation code. Will remove them after dealing with
release 6.

Both instruction encoding and test cases are generated form MIPS's internal
architecture validation tools so they are gureented to be correct.

Thanks.

- Jiaxun
