We need to deref any references passed in the `$values` array. While
we could handle this in the type switch, doing it right away in the
foreach loop makes that more explicit, and also circumvents the missing
range checks for integers which are not passed as int or double.

This fix corrects a behavior of `var_export()` that was mostly "hidden" until PHP 8.1 introduced:
* properties with object initializers
* constants containing object references
* default values of class properties containing `enum`s
Since `var_export(..., true)` is mostly used in conjunction with code generation,
and we cannot make assumptions about the generated code being placed in the root
namespace, we must always provide the FQCN of a class in exported code.
For example:
```php
<?php
namespace MyNamespace { class Foo {} }
namespace { echo "<?php\n\nnamespace Example;\n\n" . var_export(new \MyNamespace\Foo(), true) . ';'; }
```
produces:
```php
<?php
namespace Example;
MyNamespace\Foo::__set_state(array(
));
```
This code snippet is invalid, because `Example\MyNamespace\Foo::__set_state()` (which
does not exist) is called.
With this patch applied, the code looks like following (valid):
```php
<?php
namespace Example;
\MyNamespace\Foo::__set_state(array(
));
```

As it is now, `IntlTimeZone`, `IntlCalendar` and `IntlDateFormatter`
and some other intl class instances can be serialized, but the
representation is meaningless, and unserialization yields uninitialized/
unusable objects. To prevent users from noticing this too late, we deny
serialization of such objects in the first place.
Closes GH-7945.
This is being passed to convert_cp(), and passing an uninitialized
value to a function is undefined behavior. Clang 14 makes use of
noundef facts aggressively and miscompiles this code if not
initialized.

Add more specific array return type hints for various extensions - part 2
Add the --generate-optimizer-info option to the help of gen_stub.php
