Original commit message:
    The CallICStub has call-site specific knowledge about the receiver,
    which we did not utilize; plus the CallICStub does in some case know
    whether it is about to [[Call]] a function or potentially some other
    callable. In the common case we actually know that the target is a
    function and so we can use the CallFunction builtin directly instead
    of redispatching in the Call builtin.
