test commit: [bbd1bb4](https://github.com/llvm/llvm-project/commit/bbd1bb40573dd5a36dc04af4ad307d6e16456f89)
step to reproduce:
```
mlir-opt test.mlir --remove-dead-values
```
test case:
```
module {
llvm.func @malloc(i64) -> !llvm.ptr attributes {sym_visibility = "private"}
func.func private @main(%arg0: tensor<4x4xf32>, %arg1: tensor<*xf32>, %arg2: tensor<*xf32>, %arg3: tensor<2x3xi32>, %arg4: tensor<2x3xi32>) -> memref<4x1xf32> attributes {arm_streaming_compatible, pattern_driver_all_erased = true, pattern_driver_changed = false} {
%0 = llvm.mlir.constant(0 : index) : i64
%1 = llvm.mlir.poison : !llvm.struct<(ptr, ptr, i64, array<1 x i64>, array<1 x i64>)>
%2 = llvm.call @malloc(%0) : (i64) -> !llvm.ptr
%3 = llvm.insertvalue %2, %1[0] : !llvm.struct<(ptr, ptr, i64, array<1 x i64>, array<1 x i64>)>
%4 = builtin.unrealized_conversion_cast %3 : !llvm.struct<(ptr, ptr, i64, array<1 x i64>, array<1 x i64>)> to memref<4xf32>
%5 = builtin.unrealized_conversion_cast %0 : i64 to index
cf.br ^bb1(%5 : index)
^bb1(%6: index): // 2 preds: ^bb0, ^bb2
%7 = builtin.unrealized_conversion_cast %6 : index to i64
%8 = llvm.icmp "slt" %7, %0 : i64
llvm.cond_br %8, ^bb2, ^bb3
^bb2: // pred: ^bb1
%9 = builtin.unrealized_conversion_cast %6 : index to i64
%10 = builtin.unrealized_conversion_cast %9 : i64 to index
cf.br ^bb1(%10 : index)
^bb3: // pred: ^bb1
%expand_shape = memref.expand_shape %4 [[0, 1]] output_shape [4, 1] : memref<4xf32> into memref<4x1xf32>
return %expand_shape : memref<4x1xf32>
}
}
```
