----------
Use isset before array_key_exists
Small performance improvment when using
```
{% set foo = foo|default("bar") %}
```
Will render the following code
```
$context["foo"] = (((isset($context["foo"]) || array_key_exists("foo", $context))) ? (_twig_default_filter((isset($context["foo"]) || array_key_exists("foo", $context) ? $context["foo"] : (function () { throw new Twig_Error_Runtime('Variable "foo" does not exist.', 1, $this->source); })()), "bar")) : ("bar"));
```
instead of
```
$context["foo"] = ((array_key_exists("foo", $context)) ? (_twig_default_filter((isset($context["foo"]) || array_key_exists("foo", $context) ? $context["foo"] : (function () { throw new Twig_Error_Runtime('Variable "foo" does not exist.', 1, $this->source); })()), "bar")) : ("bar"));
```
