Nikita Popov d92229d8c7 Implement named parameters
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.
