UseListShuffleVector: Remove copy constructor

Browse Source 
Remove the copy constructor added in r214178 to appease MSVC17 since it
shouldn't be called at all.  My guess is that explicitly deleting it
will make the compiler happy.  To round out the operations I've also
deleted copy assignment and added move assignment.  Otherwise no
functionality change.
