The regressions would still appear unless final solution for non-power-of-2 is landed. Even after this there might be the issues with the cost model. What is the actual cause of the regression? The code was vectorized before but then it did not? There are couole regressions in reductiins, caused bya bit dufferent processing  order, they should go away with the final code for reductions and non-power-of2.
