[x86/slh] Add unwind info to several tests to make it more obvious that
we aren't incorrectly generating any of it when doing SLH. There was a bug that only occured with SLH that very much looked like it could be caused by bad unwind info, and so this was a prime suspect. Turns out that everything is fine, but this way we'll *see* if we end up, for example, putting things we shouldn't inside the prolog. llvm-svn: 338480
