Fix bug #11335 View redefines TinyInt(1) column definition
Item_type_holder doesn't store information about length and exact type of
original item which results in redefining length to max_length and geometry
type to longtext.
Changed the way derived tables except unions are built. Now they are created
from original field list instead of list of Item_type_holder.
