[jit] doctrine migrations behave weird and result in random errors and hanging processes

Description

The following code: https://github.com/verfriemelt-dot-org/doctrine-migrations-repro

Resulted in this output:

$ php -d opcache.jit=on bin/console doc:mi:mi -vv --no-interaction
[notice] Migrating up to DoctrineMigrations\Version_1000
[info] ++ migrating DoctrineMigrations\Version_0001
[debug] CREATE TABLE tab_0001 ()
[info] Migration DoctrineMigrations\Version_0001 migrated (took 22.3ms, used 10M memory)
[info] ++ migrating DoctrineMigrations\Version_0002

***hangs at 100% cpu***

or fails with strange errors instead. disabling jit does solve the issue. check out the reproducer, which results in the hanging process, on a private project it fails with

In TableDoesNotExist.php line 16:

  [Doctrine\DBAL\Schema\Exception\TableDoesNotExist]
  There is no table with name "customer_anonymisation_request" in the schema.

which is completly unrelated to the migration, so i expect this to be a jit bug rather than a bug in doctrine 🤔

Beginne mit dem verknüpften doctrine-migrations-repro-Projekt und führe den bereitgestellten bin/console doc:mi:mi-Befehl mit PHP 8.5.3 und aktiviertem opcache.jit aus; vergleiche ihn anschließend mit deaktiviertem JIT. Verfolge den Fehler vom OPcache-JIT-Pfad durch die Einträge des Migrationsstapels und stelle eine reproduzierbare, JIT-spezifische Ursache für den Hänger oder den nicht zusammenhängenden Schemafehler fest.
