Aleksey Midenkov 49d1bf71dc MDEV-33985 Server crashes at Item_func_nextval::val_int 
Pure aliases are not handled properly by Item_func_nextval::val_int().

add_table_to_list() does not create MDL request for pure aliases,
i.e. when there is no table_list->db set or TL_OPTION_ALIAS was
set. When the expression is not inside CTE the case with empty db is
handled by:

  else if (!lex->with_cte_resolution && lex->copy_db_to(&db))
    DBUG_RETURN(0);

So, table_list gets current database name and the query is failed with
ER_NO_SUCH_TABLE error.

The fix adds the case of is_pure_alias() for
Item_func_nextval::val_int() and fails it with ER_NOT_SEQUENCE2 error.

Note: semantics for TL_OPTION_ALIAS cannot be based on empty db, only
parser can set TL_OPTION_ALIAS as resolve_references_to_cte() relies
on TL_OPTION_ALIAS after copy_db_to().
