b3ad4e6118 Defer deletion of expressions that are optimized out by the AND optimizer 
in the sqlite3ExprAnd() routine until the corresponding Parse object is
deleted.  This avoids a dangling pointer in AggInfo if sqlite3ExprAnd()
is invoked by the push-down optimization.  The dangling pointer appears
to be harmless in release builds, only showing up in debug builds.
Problem found by dbsqlfuzz.

OP_ElseEq.

1e25d20cca Update sqlite3changeset_apply_v2() so that it handles no-op UPDATE changes (UPDATE changes that modify no columns). This fixes a regression introduced by [e4ccfac09b]. Also modify sqlite3rebaser_rebase() so that it does not output changesets containing such UPDATEs.

experimental as-materialize branch.
