WI-8999: Add inspection for unnecessary @noinspection comments.

On occasion, I will run into a misbehaving inspection. For an example, see WI-7659:

class MyClass
{
  protected
    /** @var SplDoublyLinkedList */
    $_nodes,
    $_index;

  public function add( $value )
  {
    $this->_nodes->push($value);
  }
}

PhpStorm's Undefined Method inspection will complain that $this->_nodes->push() is an undefined method.

I could work around this by moving the @var declaration as described in WI-7659, but since this issue is going to be fixed, I prefer just to suppress the inspection for now and remove it once PhpStorm has been updated:

class MyClass
{
  protected
    /** @var SplDoublyLinkedList */
    $_nodes,
    $_index;

  public function add( $value )
  {
    /** @noinspection PhpUndefinedMethodInspection */
    $this->_nodes->push($value);
  }
}

Once PhpStorm is updated and the Undefined Method inspection correctly recognizes $this->_nodes as an SplDoublyLinkedList, the @noinspection declaration will become superfluous. However, there will be no indicator that the @noinspection declaration can be removed.

Since these sorts of declarations do little more than clutter up my code, I would prefer to have as few of them as possible, so it would be nice if there were an inspection that would let me know when there are unnecessary @noinspection declarations in my code.
