This is a slight follow-up on #476 which reduces a bit more of the overhead for Trivial sectortypes. Additionally a slight refactor to avoid some unnecessary respecialization for contract! implementations.

@kshyatt do you know if these AMD failures are the ones from the conj thing in Strided?

I see these intermittently on 1.10 and 1.12, I think they are unrelated to this PR. We should open an issue and I'll see if I can figure out what is going wrong.
