This PR improves performance of the PropertyAccess component of ~70%.
The two main changes are:
* caching the `PropertyPath` initialization
* caching the guessed access strategy
This is especially important for the `ObjectNormalizer` (Symfony Serializer) and the JSON-LD normalizer ([API Platform](https://api-platform.com)) because they use the `PropertyAccessor` class in large loops (ex: normalization of a list of entities).
Here is the Blackfire comparison: https://blackfire.io/profiles/compare/c42fd275-2b0c-4ce5-8bf3-84762054d31e/graph
The code of the benchmark I've used (with Symfony 2.3 as dependency):
```php
<?php
require 'vendor/autoload.php';
class Foo
{
private $baz;
public $bar;
public function getBaz()
{
return $this->baz;
}
public function setBaz($baz)
{
$this->baz = $baz;
}
}
use Symfony\Component\PropertyAccess\PropertyAccess;
$accessor = PropertyAccess::createPropertyAccessor();
$start = microtime(true);
for ($i = 0; $i < 10000; ++$i) {
$foo = new Foo();
$accessor->setValue($foo, 'bar', 'Lorem');
$accessor->setValue($foo, 'baz', 'Ipsum');
$accessor->getValue($foo, 'bar');
$accessor->getValue($foo, 'baz');
}
echo 'Time: '.(microtime(true) - $start).PHP_EOL;
```
This PR also adds an optional support for Doctrine cache to keep access information across requests and improve the overall application performance (even outside of loops).

e72128f CS: Use "self" keyword instead of class name if possible
The word 'movies' was singularified to 'movy'. There seem to be only two
words ending in 'ovies', which are 'movies' and 'anchovies'. The singular
of the latter is 'anchovy'. All other words ending in 'vies' singularify to
'vy', so the word 'movies' is an exception to the general rule.

unified return null usages
| Q | A
| ------------- | ---
| License | MIT
This PR unifies the way we return `null` from a function or method:
* always use `return;` instead of `return null;` (the current code base uses both);
* never use `return;` at the end of a function/method.
