found by Akira Kurihara. The bug was caused by (- xx (float a x)) eventually becoming zero; an extra test has been added to exit the do loop when this is true. From Raymond Toy.

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.
