156c7919d9 The one-pass optimization is now working for DELETE on WITHOUT ROWID tables.

f8ffb27850 Change the interface to sqlite3GenerateConstraintChecks() for improved lucidity 
and to fix issues in dealing with UPDATEs for WITHOUT ROWID tables.  Make sure
iDataCur and iIdxCur are initialized when processing DELETEs of a VIEW.
UPDATE processing distinguishes between changes to ROWID and PRIMARY KEY.
