Test commit: https://github.com/llvm/llvm-project/commit/9e91725fd4d4ee30e98ab2682f93b423590a4ade
Steps to reproduce:
```shell
mlir-opt test.mlir -test-ir-visitors
```
Test case:
```mlir
module {
func.func private @async_execute_fn() -> !async.token attributes {passthrough = ["presplitcoroutine"]} {
%0 = async.runtime.create : !async.token
%1 = async.coro.id
%2 = async.coro.begin %1
%3 = async.coro.save %2
async.runtime.resume %2
async.coro.suspend %3, ^bb3, ^bb1, ^bb2
^bb1: // pred: ^bb0
cf.br ^bb2
^bb2: // 2 preds: ^bb0, ^bb1
cf.br ^bb3
^bb3: // 2 preds: ^bb0, ^bb2
return %0 : !async.token
}
}
```
