+1 to what @kuhar suggested. I think the only missing pattern is to fold:
```
  %0 = vector.constant_mask [2] : vector<4xi1>
  %1 = vector.extract %0[0] : i1 from vector<4xi1>
```
into the specific constant value:
```
  %0 = arith.constant 1 : i1
```

The rest of the folding that you are looking for should happen automatically after that.
