[mlir] fix assertion failure in remove-dead-values (#144849)

Simple IR patterns will trigger assertion error:

```
  func.func @test_zero_operands(%I: memref<10xindex>, %I2: memref<10xf32>) {
    %v0 = arith.constant 0 : index
    %result = memref.alloca_scope -> index {
      %c = arith.addi %v0, %v0 : index
      memref.store %c, %I[%v0] : memref<10xindex>
      memref.alloca_scope.return %c: index
    }
    func.return
  }
```

with error: `mlir/include/mlir/IR/Operation.h:988:
mlir::detail::OperandStorage& mlir::Operation::getOperandStorage():
Assertion `hasOperandStorage && "expected operation to have operand
storage"' failed.`

This PR will fix this issue.
