Bug was exposed by r213816
https://github.com/gcc-mirror/gcc/commit/ea48ac017975b0f0d4bd1ebd4b25fc658ba5f033
The bug is because we are not checking for the return value of the min/max
operations, that could return infinity when the problem is not bounded.
The new interface of ISL for integers returns an isl_val "infty" that is not
handled by the code.
Testing a fix that enables gcc to pass bootstrap with graphite flags enabled.
