Update call to cloog_loop_simplify to handling of 0D problems
Commit
f8b6a41 (Handle 0D problems by adding a 0th level to the main
recursion, Fri Oct 3 23:19:23 2008 +0200) introduced a 0th level
in cloog_loop_generate and cloog_clast_create, but it failed to update
cloog_loop_simplify accordingly. This went unnoticed because the "level"
was not used inside cloog_loop_simplify until
5f6c710 (Optionally store
domains of scattering dimensions in clast for, Mon Nov 29 18:19:38 2010 -0500).
