Issue: https://github.com/php/php-src/issues/11724
Author: jrfnl
### Description
The following code:
```php
<?php
class Foo {
private array $_GET; // OK.
}
class Bar {
public function __construct( private array $_GET ) {} // Same thing, but using CPP syntax sugar
results in fatal error.
}
```
Resulted in this output:
```
Fatal error: Cannot re-assign auto-global variable _GET in /in/ZA5Bk on line 8
```
But I expected this output instead:
_No error, fatal or otherwise._
### Additional context
Since PHP 5.4, parameter names shadowing superglobals are forbidden. However, this restriction does
not apply to property names.
When using the constructor property promotion, that restriction is, however, applied to properties
too.
### PHP Version
PHP 8.0+
### Operating System
_No response_
