[Polly] Fix long loop due to unsigned warparound. After the update to ISL to isl-0.22.1-87-gfee05a13 and its change of isl_*_dim returning -1 instead of 0, the -1 got wrapped-around to UINT_MAX because Polly often uses 'unsigned' type to represent dimensions, as ISL did before this patch. This may happen in normal executions after an out-of-quota. Fix by catching the error-case earlier. GitOrigin-RevId: 1ef55ac96e9d58572cb5a488a7eeceb3137cce9f
