These cause cache misses due to global access, in phpstan (notably the array_map). Initializing these isn't necessary because ZPP initializes it for us. Only for optional arguments do we need to be careful; for `array_filter` we still reset the `fci` but not `fci_cache` because `fci` is not necessarily set by ZPP but is conditionally used to access `fci_cache`.
