[PATCH] New ia64 @slotcount pseudo func (4th try)

[Douglas B Rupp]

Seems like from this comment rs_align_code could be handled in 
frag_offset_fixed_p, no?

   /* Align code.  The fr_offset field holds the power of 2 to which
      to align.  This type is only generated by machine specific
      code, which is normally responsible for handling the fill
      pattern.  The fr_subtype field holds the maximum number of
      bytes to skip when aligning, or 0 if there is no maximum.  */
   rs_align_code,
