   @jianxind please see my e-mail.  I think we should try to split this PR up into runtime dispatch using slightly tweaked version of the current code without intrinsics.  I will take a closer look at what is being done for sparse, but if you aren't using BitBlockCounter we should incorporate that as a first step, so most sums can delegate to Dense
