Test on commit: https://github.com/llvm/llvm-project/commit/333ae0a6c4d2209e3b8c6c672986a52644bd5baf
steps to reproduce:
```
mlir-opt -test-ir-visitors test.mlir
```
test case:
```
module {
func.func @main(){
%c0 = arith.constant 0 : index
%c68 = arith.constant 68 : index
cf.br ^bb1(%c0 : index)
^bb1(%29: index): // 2 preds: ^bb0, ^bb2
%30 = builtin.unrealized_conversion_cast %29 : index to i64
%31 = arith.cmpi slt, %29, %c68 : index
return
}
}
```
crash trace:
```
test.mlir:4:12: error: 'arith.constant' op operation destroyed but still has uses
%c68 = arith.constant 68 : index
^
test.mlir:4:12: note: see current operation: %0 = "arith.constant"() {value = 68 : index} : () -> index
test.mlir:8:11: note: - use: %1 = "arith.cmpi"(%arg0, <<UNKNOWN SSA VALUE>>) {predicate = 2 : i64} : (index, index) -> i1
%31 = arith.cmpi slt, %29, %c68 : index
