If you want to IdCliente you need to return it first from the login function.

public function login($username,$password){
    $this->db->select('IdCliente,LoginCliente');
    $this->db->where('LoginCliente',$username);
    $this->db->where('PassCliente',$password);
    $q = $this->db->get('clientes');

    if($q->num_rows()>0){
        return $q->row_array();
    }else{
        return false;
    }
}

Now In Index Function:

$session_data = $this->cliente->login($_POST['username'],$_POST['password'])
if(isset($session_data) && !empty($session_data){            
        $this->session->userdata('session_data',$session_data);
        redirect('profile');
 }

At the Profile(at the View):

$session_data = $this->session->userdata('session_data');
    $IdCliente= $session_data['IdCliente'];
    $LoginCliente= $session_data['LoginCliente'];
