php-in-php: opendir/readdir — delete phpc_dir.c + phpc_fs_dir.c, JIT from ext/standard #5258

Category

Problem

Directory handle builtins (opendir, readdir, closedir, rewinddir) are tracked in #3653, but JIT/AOT still use C state machines in lib/AOT/runtime/phpc_dir.c and lib/AOT/runtime/phpc_fs_dir.c (256-handle tables, scandir(3) backing). This duplicates future PHP/VmFs work and grows the AOT link surface.

php-src reference

• php/php-src ext/standard/dir.c — php_stream_opendir, php_readdir, php_closedir, php_rewinddir

Repro

<?php
$h = opendir(__DIR__);
echo readdir($h), "\n";
closedir($h);

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php bin/vm.php repro.php 2>&1 | head -5
php bin/jit.php repro.php 2>&1 | head -5
'

(Expect VM/JIT parity once #3653 lands; this issue removes C after PHP path exists.)

Scope

Done when

• Both .c files deleted; no directory-handle symbols in AOT runtime
• JIT/AOT opendir/readdir loop matches Zend ordering (. / .. rules per php-src)
• ./script/ci-fast.sh --filter opendir green
• PR notes C lines removed
