Also even after doing that the effect of adding extra CM instance will not be seen yet because of the predicated vplans will not be created yet. Creating predicated vplans will be in a separate patch.

My plan was creating those CM-related patches and then another patch for creating predicated/tail-folded vplans, then we will be able to have unpredicated and predicated vplans. And then a final patch for emitting the final blocks for unpredicated vplan for the main vector loop and predicated vplan for the epilogue vector loop.

Please advise if you have a different view regarding how to order the patches.
