Stdlib: ldap_count_entries() JIT path throws instead of matching php-src result count (ext/ldap/ldap.c)

Problem

ldap_count_entries() works on the VM via VmLdapNative::countEntries(), but compiled JIT/AOT calls still throw LogicException from call() in ext/ldap/ldap_search_builtins.php. Compiled PHP therefore cannot walk search results even though the PHP-side runtime already exists.

Repro	Zend 8.2+	VM	JIT/AOT
ldap_count_entries($ldap, $result)	callable	callable	LogicException today

php-src reference

• php/php-src ext/ldap/ldap.c — PHP_FUNCTION(ldap_count_entries)
• php/php-src ext/ldap/ldap.stub.php — function ldap_count_entries(\LDAP\Connection $ldap, \LDAP\Result $result): int

PHP implementation target

• ext/ldap/ldap_search_builtins.php — replace the JIT stub in ldap_count_entries::call()
• ext/ldap/JitLdapResult.php + ext/ldap/LdapResultJitHelper.php — lower LDAP\Connection + LDAP\Result handles through PHP helper code
• lib/JIT/Builtin/LdapRuntime.php — register the bridge; keep behavior in PHP, no new runtime/*.c logic

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && PHP_COMPILER_ENABLE_LDAP=1 php bin/vm.php test/repro/issue_ldap_count_entries_jit.php'
./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && PHP_COMPILER_ENABLE_LDAP=1 php bin/jit.php test/repro/issue_ldap_count_entries_jit.php'

Done when

• JIT/AOT accept LDAP\Connection + LDAP\Result with php-src-strict TypeErrors on bad args
• Return is int matching VM/ldap_count_entries() (including -1 when libldap reports error)
• Targeted repro + unit coverage added
• No php-compiler-strict shortcut; no new runtime/*.c logic

Merged via #32209

JIT/AOT ldap_count_entries() now lowers through LdapResultJitHelper::countEntriesArgv (php-src ext/ldap/ldap.c). VM/JIT TypeErrors match; standalone AOT compiles the call (no LogicException) and skips the live path when libldap FFI is absent.

Verification: php bin/vm.php / php bin/jit.php repro → bad_conn=typeerror / bad_result=typeerror / ok; phpc build → fn=1 / connect=0 / ok; PHPUnit LdapCountEntries*|LdapRuntimeShrinkTest 12 tests (1 skip without live Result).
