       %P               print address for pli instruction.

       %<bitfield>d     print bitfield in decimal

       %<bitfield>`c    print specified char iff bitfield is all zeroes
       %<bitfield>?ab... select from array of values in big endian order

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