UseListOrder: Try to resolve buildbot failure

MSVC [1] thinks `UseListShuffleVector` needs a copy constructor, but I
don't.  Let's see if being explicit about `UseListOrder` is convincing.

[1]: http://lab.llvm.org:8011/builders/lld-x86_64-win7/builds/11664/steps/build_Lld/logs/stdio

Here's the failure:
