      o Fix a misplaced declaration in %unary-ftruncate/single-float · a71e3e77
      rtoy authored
      o Update %unary-ftruncate and the corresponding deftransform because
        it was not properly returning the correct sign for signed zeroes.
        If the number was in a good range, we used truncate, which loses the
        sign of zero.  (Should we have leave it in and add an explicit check
        for a zero result and adjust the sign appropriately?  That would
        allow us to use the fast builtin instructions at the expense of a
        test for zero and a fix.)

      Added %UNARY-TRUNCATE-{SINGLE,DOUBLE}-FLOAT/FIXNUM functions, but then · eafdc708
      ram authored
      commented them out, cause I decided to do this by frobbing the rounding
      modes.  They might be useful someday.
      Added %UNARY-ROUND to handle the 1-arg case of round, making it use
      the new round primitive in the fixnum result case.
      Fixed %UNARY-TRUNCATE to use open bounds when deciding whether the result
      is a fixnum, and also to only return one value in the ratio case.
