[Bug tree-optimization/114476] [13/14 Regression] wrong code with -fwrapv -O3 -fno-vector-cost-mode (and -march=armv9-a+sve2 on aarch64 and -march=rv64gcv on riscv)

--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase where we don't need -fwrapv:
```
signed int b = 9;
int c[23][23];
signed int d[23];
int main() {
  for (int h = 0; h < 23; h += 2) {
    c[h][h] = d[h];
    b= -b;
  }
  __builtin_printf("%u\n", b);
}

```
