   All hppa opcodes are 32 bits.

   The match component is a mask saying which bits must match a
   particular opcode in order for an instruction to be an instance
   of that opcode.

   The args component is a string containing one character for each operand of
   the instruction.  Characters used as a prefix allow any second character to
   be used without conflicting with the main operand characters.

   Bit positions in this description follow HP usage of lsb = 31,
   "at" is lsb of field.

   In the args field, the following characters must match exactly:

	'+,() '

   In the args field, the following characters are unused:

	'  "# %&    +-  /          :;< > @'
	'  C        LM       U   YZ[\]  '
	'   d       l              {|} '

   Here are all the characters:

	' !"#$%&'()*+-,./0123456789:;<=>?@'
	'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'
	'abcdefghijklmnopqrstuvwxyz{|}~'

Kinds of operands:
   x    integer register field at 15.
   b    integer register field at 10.
   t    integer register field at 31.
   a	integer register field at 10 and 15 (for PERMH)

   n	nullification for branch instructions
   N	nullification for spop and copr instructions
   w    12 bit branch displacement
   W    17 bit branch displacement (PC relative)
   z    17 bit branch displacement (just a number, not an address)

Completer operands all have 'c' as the prefix:

   cx   indexed load completer.
   cm   short load and store completer.
   cs   store bytes short completer.
   cZ   System Control Completer (to support LPA, LHA, etc.)
   ch	left/right half completer
   cH	signed/unsigned saturation completer
   cS	signed/unsigned completer at 21
   c*	permutation completer

   ?f   Floating point compare conditions (encoded as 5 bits at 31)

   ?a	add conditions
   ?A	64 bit add conditions
   ?@   add branch conditions followed by nullify
   ?d	non-negated add branch conditions

	(for 0xe format FP instructions)

   r	5 bit immediate value at 31 (for the break instruction)
	(very similar to V above, except the value is unsigned instead of
	low_sign_ext)
   R	5 bit immediate value at 15 (for the ssm, rsm, probei instructions)
	(same as r above, except the value is in a different location)
   Q	5 bit immediate value at 10 (a bit position specified in
	the bb instruction. It's the same as r above, except the
