 Description   

This is a self-containing sub-task for MDEV-14630, to get rid of INT_ITEM references in the code specifically behind ORDER, LIMIT and PROCEDURE clauses.
We'll replace the code testing Item::type() against ITEM_INT to new methods in Item and Type_handler.

Some examples of the affected code:

if (order_item->type() == Item::INT_ITEM && order_item->basic_const_item() &&
 
    !from_window_spec)


if (item->type() != Item::INT_ITEM)
 
{
 
  my_error(ER_WRONG_SPVAR_TYPE_IN_LIMIT, MYF(0));


if (!(*param->item)->fixed && (*param->item)->fix_fields(thd, param->item))
 
{
 
  DBUG_PRINT("info", ("fix_fields() for the first parameter failed"));
 
  goto err;
 
}

There are more similar pieces.
