All of queries should return correct result even if including large number

Currently several queries cannot return correct result due to incorrect
`RangeError` handling.

First example:

```ruby
assert_equal true, Topic.where(id: [1, 9223372036854775808]).exists?
assert_equal true, Topic.where.not(id: 9223372036854775808).exists?
```

The first example is obviously to be true, but currently it returns
false.

Second example:

```ruby
assert_equal topics(:first), Topic.where(id: 1..9223372036854775808).find(1)
```

The second example also should return the object, but currently it
raises `RecordNotFound`.

It can be seen from the examples, the queries including large number
assuming empty result is not always correct.

Therefore, This change handles `RangeError` to generate executable SQL
instead of raising `RangeError` to users to always return correct
result. By this change, it is no longer raised `RangeError` to users.
