      For large numbers we did not check for odd-valued results that needed
      to be rounded to even.

      In MAKE-COMPLEX-DOUBLE-DOUBLE-FLOAT · 1fc790b2
      rtoy authored
      o Turn off :load-if for the real arg because the generator doesn't
        handle the case if the real arg is on the stack.
      o Enable :load-if for the result because the code (already) handled
        it.
      o The wrong TN was being used for the imaginary part of the real part.
      o The wrong TNs were being used for the arg registers.  Use the right
        TN values.

      Better conversion of bignums to double-double-floats. Also fixes the · d61a8a8b
      rtoy authored
      silly bug that (float <neg bignum> 1w0) was returning a positive
      result instead of negative.
      
      o Rename DOUBLE-DOUBLE-FLOAT to DOUBLE-DOUBLE-FLOAT-FROM-BITS to match
        other functions and to make it separate from the same function in
        the KERNEL package.
      o Modify DOUBLE-DOUBLE-FLOAT-FROM-BITS to look at the bignum and
        extract out the pieces better.  Look for a pattern <53 bits> <zeroes>
        <53 bits> where <zeroes> is a set of consecutive zero bits.  We use
        the 2 53-bit sections to create the double-double-float.
      o Make DOUBLE-DOUBLE-FLOAT-FROM-BITS honor the sign.
      o Add BIGNUM-FLOAT-DIGITS to figure out how many bits of the bignum
        should be used to create the float.
      o Call BIGNUM-FLOAT-DIGITS from BIGNUM-TO-FLOAT instead of using
        FLOAT-FORMAT-DIGITS.
