Throw exception on circular reference detection
Out-the-box this isn't common... but into Symfony framework this kind of issue can happen frequently when we're overriding a template from third-party bundle (see main issue https://github.com/symfony/symfony/issues/17557)
```twig
{# app/Resources/AcmeBlogBundle/views/Blog/index.html.twig #}
{% extends '@AcmeBlog/Blog/index.html.twig' %}
{% block title 'New Title' %}
```
This exception avoids inifite loop or maximum execution time for this case, by detecting a recursive loading when a template extends from itself, thinking to override the parent template which has the same namespace + template name.

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.
