[php-src] Issue #13177: PHP 8.3.2: final private constructor not allowed when used in trait

Issue: https://github.com/php/php-src/issues/13177 Author: ondrejmirtes ### Description The following code: ```php <?php final class Foo { use Bar; } trait Bar { final private function __construct() {} } ``` Resulted in this output: ``` Warning: Private methods cannot be final as they are never overridden by other classes in /in/4sc3H on line 3 ``` But I expected this output instead: ``` No error ``` Constructors CAN be private AND final, as opposed to normal methods. This is a wrong side effect of this fix: https://github.com/php/php-src/pull/12857 Please make sure that the version with trait usage is also allowed: ```php <?php final class Foo { use Bar { __construct as final; } } trait Bar { private function __construct() {} } ``` ### PHP Version PHP 8.3.2 ### Operating System N/A
