The phiopt optimization pass now rejects cases where pointer types are incompatible, such as different address spaces or function pointers. This prevents crashes that could occur when creating a phi node with such pointers. The pass could be further refined to support specific address space differences, but the current change prioritizes stability by avoiding the more complex scenarios.
