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 @test_broadcast19(%arg0: tensor<64x64x1xf32> {bufferization.access = "read"}, %arg1: tensor<1x17xf32> {bufferization.access = "read"}) -> tensor<64x64x17xf32> {
%0 = tosa.sub %arg0, %arg1 {__inplace_operands_attr__ = ["false", "false"]} : (tensor<64x64x1xf32>, tensor<1x17xf32>) -> tensor<64x64x17xf32>
return {__inplace_operands_attr__ = ["true"]} %0 : tensor<64x64x17xf32>
}
func.func @main(%arg0: tensor<64x64x1xf32> {bufferization.access = "read"}, %arg1: tensor<1x17xf32> {bufferization.access = "read"}, %cond : i1) -> (tensor<64x64x17xf32>) {
%0 = call @test_broadcast19(%arg0, %arg1) {__inplace_operands_attr__ = ["true", "true"]} : (tensor<64x64x1xf32>, tensor<1x17xf32>) -> tensor<64x64x17xf32>
cf.cond_br %cond, ^bb_true, ^bb_false
^bb_true: // True branch
// Here we could further process with results or call an operation
return {__inplace_operands_attr__ = ["true"]} %0 : tensor<64x64x17xf32>
^bb_false: // False branch
return {__inplace_operands_attr__ = ["true"]} %0 : tensor<64x64x17xf32>
}
}
```
