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.
