* Fix performance regression in quotRemInteger/divModInteger
This fixes most of the performance regression in these functions
between 6.8.3 and 6.10.1, it was due to a slight difference in the
strictness between the old and new versions (see comments for
details). There's still a few percent loss in performance in the div
test in nofib/spectral/integer that I haven't tracked down as yet.
