----------
Use class_exists instead of require
I think this is required for https://github.com/symfony/symfony/pull/23073 to pass. It's probably very similar to https://github.com/symfony/symfony/pull/22657.
A simple reproducer:
```php
<?php
use Twig\Node\Node;
require_once __DIR__ . '/vendor/autoload.php';
new Node();
new \Twig_Node();
```
[Without this patch](https://travis-ci.org/symfony/symfony/jobs/239712676#L2100):
```php
PHP Fatal error: Cannot declare class Twig_Node, because the name is already in use in vendor/twig/twig/lib/Twig/Node.php on line 20
```
With, everything works fine, whatever the two calls order.
