**Describe the bug**

-2147483648 is the minimum integer representable with Int32, but ``toInt32OrNull('-2147483648')`` returns ``NULL``. On the other hand ``toInt32('-2147483648')`` correctly returns ``-2147483648``.

**Does it reproduce on recent release?**

Yes. It happens on 21.7.5.29-stable

**How to reproduce**

```
SELECT
    toInt32('-2147483648'),
    toInt32OrNull('-2147483648')

Query id: 94f4e069-6c0e-44d9-8e94-7ee83b90a529

┌─toInt32('-2147483648')─┬─toInt32OrNull('-2147483648')─┐

└────────────────────────┴──────────────────────────────┘
```

**Expected behavior**

``toInt32('-2147483648')`` and ``toInt32OrNull('-2147483648')`` should both return ``-2147483648``.
