    d: Clean-up unused variable assignments after interface change
    
    The lowering done for invoking `new' on a single dimension array was
    moved from the code generator to the front-end semantic pass in
    r14-4996.  This removes the detritus left behind in the code generator
    from that deletion.
    
    gcc/d/ChangeLog:
    
            * expr.cc (ExprVisitor::visit (NewExp *)): Remove unused assignments.
