This revision is now accepted and ready to land.

This patch indirectly causes the vectoriser to choose a lower VF due to the high cost of extending nxv16i8 -> nxv16i16, and that caused a regression.
Dave was investigating that issue and he has created a patch for fixing it.
So, right now this patch should work well.
I will rebase it and run checks to make sure everything is okay.
