   With one exception at the bottom (done because BL and BLX(1) need
1367
   to come dead last), this table was machine-sorted first in
1368
   decreasing order of number of bits set in the mask, then in
1369
   increasing numeric order of mask, then in increasing numeric order
1370
   of opcode.  This order is not the clearest for a human reader, but
1371
   is guaranteed never to catch a special-case bit pattern with a more
1372
   general mask, which is important, because this instruction encoding
1373
   makes heavy use of special-case bit patterns.  */
