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.

f01dae1f32 Additional steps to help ensure that scalar subqueries are only evaluated

a performance regression reported on the mailing list and caused by

[787fa716be3a7f650c]. Think of this check-in as an improved fix for
that ticket.

ec4ccdbcb1 A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer 
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*.
