Sure, but for these strides these patches only finish the few missing pieces,
while after codegen improves we may optionally have to go back and update the costs
and a few more items to update won't really affect things.
The next big batch (stride=5/7/8) can indeed wait a bit for better codegen.

After these, hopefully D111460 <https://reviews.llvm.org/D111460> lands, and then i think i'd like to decide on discounting not-fully-interleaved loads before finishing with the missing strides.
