[php-src] Issue #12748: Function JIT emits "could not convert to int" warning at the same time as invalid offset Error

Issue: https://github.com/php/php-src/issues/12748 Author: Girgias ### Description The following code: ```php <?php $container = "string"; // Is try { echo "isset():\n"; var_dump(isset($container[new stdClass()])); } catch (\Throwable $e) { echo $e->getMessage(), "\n"; } try { echo "empty():\n"; var_dump(empty($container[new stdClass()])); } catch (\Throwable $e) { echo $e->getMessage(), "\n"; } try { echo "Coalesce():\n"; var_dump($container[new stdClass()] ?? 'default'); } catch (\Throwable $e) { echo $e->getMessage(), "\n"; } ?> ``` Resulted in this output: ``` isset(): bool(false) empty(): bool(true) Coalesce(): Warning: Object of class stdClass could not be converted to int in %s on line %d Cannot access offset of type stdClass on string ``` But I expected this output instead: ``` isset(): bool(false) empty(): bool(true) Coalesce(): Cannot access offset of type stdClass on string ``` Related to https://github.com/php/php-src/pull/12723 ### PHP Version PHP 8.2 ### Operating System _No response_
