intel/ir: Drop hard-coded correspondence between IR and HW opcodes.
Having the IR opcodes locked to their hardware representation is risky because it causes opcodes as different as BRC and IFF to compare equal at the IR level (luckily the back-end only ever uses one opcode from each group, right now), and it prevents us from supporting instructions that change their hardware representation across generations, which will become a problem on Gen12+ platforms.
