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.

memory allocations by deferring memory allocation until
sqlite3VdbeResolveLabel() is called, at which point the code generator has
a better idea of how big the relocation table needs to be.
The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of
Vdbe*.
