Currently, yes. However, by the time we enter ZEND_DO_FCALL, we know
which function we're going to call. And at compile time, we know how
many arguments exist.

We can also move the argument verification from RECV into
ZEND_DO_FCALL just like happens today with internal functions. In
fact, it may be worthwhile investigating that in general.
