Bug #27300:
Geometry fields have a result type string and a
special subclass to cater for the differences
between them and the base class (just like
DATE/TIME).
When creating temporary tables for results of
functions that return results of type GEOMETRY
we must construct fields of the derived class
instead of the base class.
Fixed by creating a GEOMETRY field (Field_geom)
instead of a generic BLOB (Field_blob) in temp
tables for the results of GIS functions that
have GEOMETRY return type (Item_geometry_func).
