Test on commit: https://github.com/llvm/llvm-project/commit/a9882bda96228ca23e166a817f93a7dbc99763cb
steps to reproduce:
```
mlir-opt test.mlir -test-ir-visitors
```
test case:
```
module {
func.func @canonicalize_parallel_insert_slice_indices(
%arg0 : tensor<1x5xf32>,
%arg1: tensor<?x?xf32>,
%num_threads : index) -> tensor<?x?xf32>
{
%cst = arith.constant 4.200000e+01 : f32
%c0 = arith.constant 0 : index
%c1 = arith.constant 1 : index
%2 = scf.forall (%tidx) in (%num_threads) shared_outs(%o = %arg1) -> (tensor<?x?xf32>) {
%3 = tensor.cast %arg0 : tensor<1x5xf32> to tensor<?x5xf32>
scf.forall.in_parallel {
tensor.parallel_insert_slice %3 into %o[%tidx, %c0] [%c1, 5] [%c1, %c1] : tensor<?x5xf32> into tensor<?x?xf32>
}
}
return %2 : tensor<?x?xf32>
}
}
```
