[LLVMdev] associating id with opcodes

[Bruno Cardoso Lopes]

I don't know if the approach I'm thinking is enough for the use you
wanna do, but if you want something MC level, you can use MCInstrDesc
to pass some info through TSFlags. Look how X86 does with the REX
prefix in X86InstrFormats.td and X86InstrInfo.h.
