Bail in bounds_of_var_in_loop if scev returns NULL.
Both initial_condition_in_loop_num and evolution_part_in_loop_num
can return NULL. This patch exits if either one is NULL. Presumably
this didn't happen before, because adjust_range_with_scev was called
far less frequently than in ranger, which can call it for every PHI.
