[Inductor] atomic_add does not support bf16
Labels: triaged, oncall: pt2, module: inductor

### 🐛 Describe the bug

This is may be known already, but triton does not support `atomic_add` with bf16, see https://github.com/openai/triton/blob/c9740f0870f6ae2480acd2a76a5fb4c920bc5ce5/python/triton/language/semantic.py#L904.

This is not a problem in eager mode, only with `torch.compile` as it works right now, ideally this op should not be currently selected?

I made a minified repro below, but there is probably an even easier way to replicate this, I'm just unsure how to exactly trigger `atomic_add`. 

### Error logs

```
    raise ValueError("atomic_" + op + " does not support " + str(element_ty))
ValueError: atomic_add does not support bf16

The above exception was the direct cause of the following exception:
```

```
