isl_map_affine_hull: make stride information explicit before dropping divs
In a2cbe44 (isl_map_affine_hull: avoid computing explicit representations
for divs, Sun Jan 15 16:12:59 2012 +0100), isl_map_affine_hull was changed
to drop unknown divs rather than computing an explicit representation
for them. This caused some stride information that involves multiple
unknown divs to get dropped.
Try and recover this lost information by making stride information
explicitly available before dropping the unknown divs.
