%<bitfield>G print as an iWMMXt general purpose or control register
%<bitfield>D print as a NEON D register
%<bitfield>Q print as a NEON Q register
+ %<bitfield>E print a quarter-float immediate value
%y<code> print a single precision VFP reg.
Codes: 0=>Sm, 1=>Sd, 2=>Sn, 3=>multi-list, 4=>Sm pair
%<bitfield>'c print specified char iff bitfield is all ones
%<bitfield>`c print specified char iff bitfield is all zeroes
%<bitfield>?ab... select from array of values in big endian order

%L print as an iWMMXt N/M width field.
%Z print the Immediate of a WSHUFH instruction.
%l like 'A' except use byte offsets for 'B' & 'H'
