4fb282fec5 [CSKY] Add CSKY 16-bit instruction format and encoding
CSKY is a ARCH which supports mixture of 16-bit and 32-bit instructions natively,
and there is not an indivual predictor or feature to enable/disable 16-bit instruction.
So I think it's better to add 16-bit instruction early, and naturally to use 16-bit and 32-bit instructions.
