1467 decreasing order of number of bits set in the mask, then in
1468 increasing numeric order of mask, then in increasing numeric order
1469 of opcode. This order is not the clearest for a human reader, but
1470 is guaranteed never to catch a special-case bit pattern with a more
1471 general mask, which is important, because this instruction encoding
1472 makes heavy use of special-case bit patterns. */
