Especially for operands (of which there may be up to 5 right now,
and the number is only going to grow) it is quite wasteful to have
unnecessarily many attribute bits. The long term goal is to get this
count down to no more than 32. The two patches here are another two
small steps towards this.
1: fold SReg{2,3}
2: make RegMem an opcode modifier
