This seems to break the Python bindings, since now both the arith and llvm dialects define `IntegerOverflowFlags`:

```
Traceback (most recent call last):
  ...
File "[...]/mlir/ir.py", line 14, in decorator_builder
    AttrBuilder.insert(kind, func, replace=replace)
RuntimeError: Attribute builder for 'IntegerOverflowFlags' is already registered with func: <function _integeroverflowflags at 0x7faf26f8ce00>
```

The repro is

```
from mlir.dialects import arith, llvm
```
