Test on commit: [c3edeaa61bf0e7faed6c26f693b4fcd9102ba1ec](url)
steps to reproduce:
```
mlir-opt test7.mlir --test-ir-visitors
```
test case:
```
module {
func.func @branchCondProp(%arg0: i1) {
llvm.cond_br %arg0, ^bb1, ^bb2
^bb1: "test.consumer1"(%arg0) : (i1) -> ()
^bb2: "test.consumer2"(%arg0) : (i1) -> ()
return
}
}
```
