php-in-php: JIT array_intersect_key — ArrayIntersectKeyJitHelper PHP (#12551)

[PurHur]

Summary

• JIT embed array_intersect_key() routes through ArrayIntersectKeyJitHelper → VmArray::intersectKeyTwo() instead of ArrayBuiltinHelper::arrayIntersectKey() LLVM (php-in-php: JIT array_intersect_key — route embed LLVM through ArrayIntersectKeyJitHelper PHP (#1492 slice 20) #12551, slice 20).
• Standalone AOT keeps LLVM quarantine path unchanged.

php-src reference

• ext/standard/array.c — PHP_FUNCTION(array_intersect_key)

LLVM shrink

Embed path no longer emits arrayIntersectKeyHashTable LLVM from array_intersect_key() calls; standalone retains ArrayBuiltinHelper::arrayIntersectKey().
