OK I realized for the following case it will conflict

```mlir
!test.type<a = 3> // suggest !name0
!test.type<a = 4> // suggest !name0
!test.another<b = 3> // suggest !name0_
!test.another<b = 4> // suggest !name0_1
```

The result now would be

```
!name0
!name0_1
!name0_2
!name0_1
```

I think such detection could be made by tarvering `nameCount`, but that will bring some overhead. Will attach a possible fix below.
