418454c63f For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a 
REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign
key constraints that causes SQLite to clobber any existing row without
separately checking for it. This optimization causes SQLite to omit the
expected pre-update-hook callbacks.

The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of
Vdbe*.
