I have now remembered why I've added this in the first place. Without
this, gcc calls __divsi3 instead of $sldiv (the DImode division
subroutine) in the following function:

typedef int T __attribute ((mode (HI)));

T f (T x, T y) { return x/y; }

It doesn't do that if I change T to QImode or SImode or if I add the
pattern you've removed. This isn't supposed to happen, right? I'll try to
find out where gcc gets confused.
