Hmmmm, I am not sure if the complexity is really worth it.

In any case, [PATCH 1/2] is fairly uncontroversial, so I am inclined
to queue it by itself early without waiting for the discussion on
2/2 to settle.

That naming assumes that there will never be any alternative
implementation of the bytewise checker other than the one that uses
sse42, no?

If we foresee people on other architectures to invent different
vectorized implementations on their favourite archs, we may end up
separating it out into compat/.  I have no opinion on how likely
that will happen, though, and because this is a small piece of code
right now, it shouldn't be too painful to reorganize when the time
