    Delete Ord Unique
    
    Ord Unique can be a source of invisible, accidental
    nondeterminism as explained in Note [No Ord for Unique].
    This removes it, leaving a note with rationale.
    
    It's unfortunate that I had to write Ord instances for
    codegen data structures by hand, but I believe that it's a
    right trade-off here.
    
    Test Plan: ./validate
