Respect mixed return and raise cases in return-type analysis (#9310)
## Summary

Given:

```python
from somewhere import get_cfg

def lookup_cfg(cfg_description):
    cfg = get_cfg(cfg_description)
    if cfg is not None:
        return cfg
    raise AttributeError(f"No cfg found matching {cfg_description}")
```

We were analyzing the method from last-to-first statement. So we saw the
`raise`, then assumed the method _always_ raised. In reality, though, it
_might_ return. This PR improves the branch analysis to respect these
mixed cases.
