### What problem does this PR solve? `BIGINT_MIN DIV -1` can trigger signed integer overflow in BE `int_divide` and terminate the backend with `SIGFPE`. Root cause: `DivideIntegralImpl` only handled division by zero, but did not guard the undefined signed case where the minimal signed integer is divided by `-1`. This change follows the existing `mod`/`pmod` behavior and returns `INVALID_ARGUMENT` before executing the unsafe division. The guard covers const/const, vector/const, const/vector, and vector/vector paths. https://godbolt.org/z/YPq9W581e ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
