Issue: [Fake Tensor] `.div` pass the check on inductor when divisor is zero
Labels: triaged,oncall: pt2,module: fakeTensor,module: aotdispatch,module: pt2-dispatcher

### 🐛 Describe the bug

An error is raised when the divisor is 0 on eager. However, inductor passes the check and outputs the max value of Long.

both occurs on cpu and cuda.

```python
import torch
import torch.nn as nn


class Model(nn.Module):
    def __init__(self):
        super(Model, self).__init__()

    def forward(self, x, y):
        x.div_(y)
        return x


x = torch.tensor([1])
y = torch.tensor([0])

inputs = [x, y]


def run_test(inputs, device, mode):
    model = Model()
    if mode == "inductor":
        model = torch.compile(model)

    if device == "cuda":
        inputs = [x.cuda() for x in inputs]
        model = model.cuda()

    try:
        output = model(*inputs)
        print(f"{mode} succeeds: {output}")
    except Exception as e:
        print(e)

run_test(inputs, "cuda", "eager")
run_test(inputs, "cuda", "inductor")
run_test(inputs, "cpu", "eager")
run_test(inputs, "cpu", "inductor")
```

### Error logs

```
result type Float can't be cast to the desired output type Long
inductor succeeds: tensor([9223372036854775807], device='cuda:0')
result type Float can't be cast to the desired output type Long
inductor succeeds: tensor([-9223372036854775808])
