Test case
The access description of the %tmp3 access is very complicated because of the
divisions and modulo operations. During the hoisting this will cause isl to
take "forever" to create an affine functio from the access set
(isl_pw_multi_aff_from_set). We are therefore stuck in
IslNodeBuilder::preloadUnconditionally.</pre>
