unknown a292b42436 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.
