2517 With one exception at the bottom (done because BL and BLX(1) need
2518 to come dead last), this table was machine-sorted first in
2519 decreasing order of number of bits set in the mask, then in
2520 increasing numeric order of mask, then in increasing numeric order
2521 of opcode. This order is not the clearest for a human reader, but
2522 is guaranteed never to catch a special-case bit pattern with a more
2523 general mask, which is important, because this instruction encoding
2524 makes heavy use of special-case bit patterns. */
