This bug only bit the C++98 build bots because all of the actual uses
really do move. ;] But not *quite* ready to do the whole C++11 switch
yet, so clean it up. Also add a unit test that catches this immediately.

r-value references. I still want to test that when we have them,
llvm_move is actually a move.
Have I mentioned that I really want to move to C++11? ;]

Clang managed to never instantiate the copy constructor. Added tests to
ensure this path is tested.
We could still use tests for the polymorphic nature. Those coming up
next.

unique ownership smart pointer which is *deep* copyable by assuming it
can call a T::clone() method to allocate a copy of the owned data.
This is mostly useful with containers or other collections of uniquely
owned data in C++98 where they *might* copy. With C++11 we can likely
remove this in favor of move-only types and containers wrapped around
those types.
