isl_affine_hull.c: only construct affine hull in bounded directions
The affine hull of a set necessarily contains the directions
of the recession cone of the set.
Before we exploited this fact by adding these directions to
our initial approximation of the affine hull.
The set for which the affine hull was computed was not changed, however.
Now, we project out the recession cone and only construct an
affine hull in the remaining part.
