Michael Kruse 1ef55ac96e [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.
