I've used this snippet of code to populate the default values for the en locale:

```php
for ($style = 0; $style <= 8; $style++) {
    $f = new \NumberFormatter('en', $style);
    echo 'array(';
    for ($i = 0; $i <= 17; $i++) {
        echo "'".$f->getSymbol($i)."', ";
    }

    echo "),\n";
}
```

Broken in #7940 (67ba1314580ad63cbbf923b59157f226210d62ce). Since benchmark tests are not run on travis, it didn't complain.

Yet another approach to running all tests in parallel (see #7708 and #8312).

This one uses [GNU Parallel](http://www.gnu.org/software/parallel/) which by default [will run one job per available CPU](http://www.gnu.org/software/parallel/man.html#jobs_n).

Comparison of random builds (recent build times on my travis account):

| PHP version| [master](https://travis-ci.org/jakzal/symfony/builds/11300678)             |  [parallel](https://travis-ci.org/jakzal/symfony/builds/11300689)
| ------------- | --- | ---
| 5.3.3| 6 min 11 sec | 3 min 45 sec
| 5.3| 7 min 26 sec | 4 min 10 sec
| 5.4| 6 min 31 sec | 3 min 31 sec
| 5.5| 6 min 37 sec | 3 min 45 sec

On my laptop it takes 1.5min to run a whole suite parallelised (compared to over 4min when run as usual).

Fixes this bug:
```php
$cookieJar = new CookieJar();
$cookieJar->set(new Cookie('foo', 'bar', null, '/', '.example.com'));

print_r($cookieJar->allValues('http://wwwexample.com'));
// expected result: array()
// actual result: array('foo' => 'bar')
```
