  Implemented a complete redesign of MLRISC pseudo-ops. Now there
  ought to never be any question of incompatabilities with
  pseudo-op syntax expected by host assemblers.

  For now, only modules supporting GAS syntax are implemented
  but more should follow, such as MASM, and vendor assembler
  syntax, e.g. IBM as, Sun as, etc.

  Fix for a backpatching bug reported by Allen.

  Because the boundary between short and long span-dependent
  instructions is +/- 128, there are an astounding number of
  span-dependent instructions whose size is over estimated.

  Allen came up with the idea of letting the size of span
  dependent instructions be non-monotonic, for a maxIter
  number of times, after which the size must be monotonically
  increasing.

  This table shows the number of span-dependent instructions
  whose size was over-estimated as a function of maxIter, for the
  file Parse/parse/ml.grm.sml:

     maxIter		# of instructions:
 	10			687
 	20			438
 	30			198
        40			  0

  In compiling the compiler, there is no significant difference in
  compilation speed between maxIter=10 and maxIter=40. Actually,
  my measurements showed that maxIter=40 was a tad faster than
  maxIter=10! Also 96% of the  files in the compiler reach a fix
  point within 13 iterations, so fixing maxIter at 40, while high,
  is okay.

   A CVS update record!

   Changed type cell from int to datatype, and numerous other changes.
   Affect every client of MLRISC.  Lal says this can be bootstrapped on all
   machines.  See smlnj/HISTORY for details.
