From an engine perspective, named parameters mainly add three concepts: * The SEND_* opcodes now accept a CONST op2, which is the argument name. For now, it is looked up by linear scan and runtime cached. * This may leave UNDEF arguments on the stack. To avoid having to deal with them in other places, a CHECK_UNDEF_ARGS opcode is used to either replace them with defaults, or error. * For variadic functions, EX(extra_named_params) are collected and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS. RFC: https://wiki.php.net/rfc/named_params Closes GH-5357.
