First you will need to get the permissions for the user (XenForo_Visitor::getInstance()->toArray()["permissions"]), then use XenForo_Permissions::hasPermission(permissionArray, permissionGroup, permissionID) to check whether the user has permissions. Additionally, a shortcut XenForo_Visitor::getInstance()->hasPermission(permissionGroup, permissionID) is also available.

I highly recommend you to dig around XF's code to see it in action.

Here's an example from my Show Deleted add-on.

In this case I'm checking to see if the user has the permission to view soft deleted posts and threads.

    // get permissions
     $permissions = XenForo_Visitor::getInstance()->getPermissions();
     // get viewDeleted permission
     $viewDeleted = XenForo_Permission::hasPermission($permissions, "forum", "viewDeleted");
     // if viewDeleted is false display no permission response
     if (!$viewDeleted)
       throw $this->getNoPermissionResponseException();
