Currently indexes are the bulk of the problem with `UPDATE` and
`DELETE`, while we work on fixing those it makes sense to disable
indexing since they are not stable. We want to try to make everything
else stable before we continue with indexing.
- `Update` query doesn't update `n_changes`. Let's make it work
- Add `InsertFlags` to add meta information related to insert operations
- For update query, add `UPDATE` flag
- Currently, the update query executes `Insn::Delete` and `Insn::Insert`
internally, it increases `n_change` by 2. So, for the update query,
let's skip increasing `n_change` for the `Insn::Insert`

this mistake in the future. this is zero-cost, and will be optimized to
the same thing (hopefully).
