### Description

Hi @dstogov,

```
php: /tmp/php-src/ext/opcache/jit/ir/ir.c:2093: _ir_RETURN: Assertion `ctx->control' failed.
```

This is another assertion failure issue I see after the integration of the new JIT. It's
reproducible with CALL VM and GCC global regs **disabled** on both x86 and AArch64. Please see below
steps for details.

**1. Checkout and build PHP with some configurations**

```
$ cd /tmp
$ git clone git@github.com:php/php-src.git
$ cd php-src
$ php Zend/zend_vm_gen.php --with-vm-kind=CALL
$ bash buildconf
$ bash configure --enable-bcmath --enable-calendar --enable-dba --enable-debug --enable-exif \
  --enable-fpm --enable-ftp --enable-gd --enable-intl --enable-mbstring
--enable-option-checking=fatal \
  --enable-pcntl --enable-phpdbg --enable-shmop --enable-soap --enable-sockets --enable-sysvmsg \
  --enable-sysvsem --enable-xmlreader --enable-zend-test --with-mysqli=mysqlnd
--with-pdo-mysql=mysqlnd \
  --disable-gcc-global-regs
$ make
```

**2. Checkout and build Laravel**

```
$ cd /tmp
$ git clone https://github.com/laravel/framework.git
$ cd framework
$ composer install
```

**3. Run Laravel tests with the PHP we just build**

```
$ cd /tmp/framework
$ /tmp/php-src/sapi/cli/php -d zend_extension=/tmp/php-src/modules/opcache.so -d \
  opcache.jit_buffer_size=128M -d opcache.enable_cli=1 vendor/bin/phpunit
PHPUnit 10.4.2 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.4.0-dev
