      Added operand type restrictions on the fixnum<=>word coercions so that · 1a3bb12e

      the new representation selsection stuff knows to only use these VOPs
      when the operands are fixnums.  An ambiguity existed because 
      CONTROL-STACK is used to store both fixnums and bignums.  Previously 
      the first-defined VOP was always used, which was wrong.

      Added stuff to allow multiple move VOPs per SC pair, with selection ebing · e9e6b283

      done by the primitive type of the operands.  Also, added stuff to delete
      moves to :NORMAL TNs that have no reads.  Changed the existing 
      special-casing of unread results to only punt on :NORMAL TNs.
      Also, fixed the move/coerce generation stuff to just leave alone the MOVEs
      that are o.k., instead of deleting the old MOVE and inserting a new one.
