Prebuild the row string to position lookup for Rows
Improved :class:`_engine.Row` implementation to optimize
``__getattr__`` performance.
The serialization of a :class:`_engine.Row` to pickle has changed with
this change. Pickle saved by older SQLAlchemy versions can still be loaded,
but new pickle saved by this version cannot be loaded by older ones.
