rubenrua 4e1887a721 Improve memory usage resolving dependencies
It is known that composer update takes a lot of memory: #5915, #5902,

I am playing with a profiler (@blackfireio) to make a demo in my local
PHP meetup (@phpvigo) and I found out a way to use less memory. These
are my first tests:

* Private project using PHP 5.6:
  * Memory: from 1.31GB to 1.07GB
  * Wall Time: from 2min 8s to 1min 33s

* symfony-demo using PHP 7.1 in my old mac book:
  * Memory: from 667MB to 523MB
  * Wall Time: from  5min 29s to 5min 28s

Not use an array inside conflict rules is this improvement main idea:

```php
<?php
//Memory 38MB
gc_collect_cycles();
gc_disable();

class Rule
{
    public $literals;

    public function __construct(array $literals)
    {
        $this->literals = $literals;
    }
}

$rules = array();

$i = 0;
while ($i<80000){ //
    $i++;

    $array = array(-$i, $i);
    $rule = new Rule($array);
    $rules[] = $rule;
}
```

```php
<?php
//Memory 11.1MB
gc_collect_cycles();
gc_disable();

class Rule2Literals
{
    public $literal1;
    public $literal2;

    public function __construct($literal1, $literal2)
    {
        $this->literal1 = $literal1;
        $this->literal2 = $literal2;
    }
}

$rules = array();

$i = 0;
while ($i<80000){ //
    $i++;

    $rule = new ConflictRule(-$i, $i);
    $rules[] = $rule;
}
```

Volker Dusch 3fb75faa75 Now that no more update rules are created the code that handles them can be removed too.
Also adapted the tests that used TYPE_UPDATE exemplarily to use TYPE_FEATURE.
