[Twig] Improve Twig types support

[Koc]

Follow-up of #972

{# @var pagerfanta \AppBundle\Entity\MeterValueDTO[] #}
{% for item in pagerfanta %}
{% endfor %}

MeterValueDTO is not clickable

{# @var \AppBundle\Entity\MeterValueDTO[] pagerfanta #}
{% for item in pagerfanta %}
{% endfor %}

item type not resolves properly because I've changed order of type and variable name. But PS supports both standards, even more second is consistent with @param declaration for methods - type first, variable name - second

Iterators call also not resolved properly:

class GeneratedReport implements \IteratorAggregat
{
    /**
     * @return Row[]
     */
    public function getIterator()
    {
        // ...
    }
}

{% for report in reports %}
    {# @var report \App\Reporting\Generated\GeneratedReport #}
    <table cellspacing="0" border="0">

        {% for row in report %}
            {{ row.<NO AUTOCOMPLETE HERE> }}
            <tr>
                {% for cell in row %}

                    <td
                            {% if cell.colspan > 1 %}colspan="{{ cell.colspan }}"{% endif %}
                            {% if cell.rowspan > 1 %}colspan="{{ cell.rowspan }}"{% endif %}
                            class="{{ cell.purpose }}"
                    >
                        {{ cell.value }}
                    </td>
                {% endfor %}
            </tr>
        {% endfor %}
    </table>
{% endfor %}

Also I've tryed write {% for row in report.getRows() %} but getRows hasn't autocomplete inside for tag. But autocompletes ok inside twig output {{ report.getRows() }}
