MLIR Program:
```

%0 = "arith.constant"() <{value = 0 : index}> : () -> index
%1 = "vector.gather"(%arg0, %0, %arg1, %arg2, %arg3) : (memref<?xindex>, index, vector<[3]xindex>, vector<[3]xi1>, vector<[3]xindex>) -> vector<[3]xindex>

Reproduce Command: `mlir-opt -convert-vector-to-xegpu a.mlir`
StackTrace:
```
