re PR tree-optimization/48189 (ICE: SIGFPE (division by zero) in in predict_loops () at predict.c:991 with --param max-predicted-iterations=0)

PR tree-optimization/48189
* predict.c (predict_loops): If max is 0, don't call compare_tree_int.
If nitercst is 0, don't predict the exit edge.

* gcc.dg/pr48189.c: New test.
