invalid assembly generated for packed struct containingunpacked struct

I think the same thing would probably happen in C if you wrote the
copies by hand, using `SBar*', so that the compiler couldn't know the
SBar is packed If not, I'm not sure why it wouldn't.  I don't think
there's any easy fix -- except to pessimize all loads and stores
involving any type that appears in a packed structure.
