Test on commit: https://github.com/llvm/llvm-project/commit/a9882bda96228ca23e166a817f93a7dbc99763cb
steps to reproduce:
```
mlir-opt test.mlir -remove-dead-values
```
test case:
```
module {
func.func @parallel_region() -> () {
%alloc0 = bufferization.alloc_tensor() : tensor<320xf32>
%alloc1 = bufferization.alloc_tensor() : tensor<1xf32>
%c320 = arith.constant 320 : index
%0 = scf.forall (%arg0) in (%c320) shared_outs(%arg1 = %alloc0) -> (tensor<320xf32>) {
%val = "test.foo"() : () -> (f32)
}
return
}
}
```
