+ %S print a possibly-shifted Rm
+

+ %w print the width and signedness of a core load/store
+ %m print register mask for ldm/stm
+
+ %E print the lsb and width fields of a bfc/bfi instruction
+ %F print the lsb and width fields of a sbfx/ubfx instruction
+ %b print a conditional branch offset

+ %s print the shift field of an SSAT instruction
+ %R print the rotation field of an SXT instruction

+
+ 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
