[VectorCombine] foldShuffleOfBinops - if both operands are the same don't duplicate the total new cost (#172719) ...

If we're shuffling/concatenating the same operands then ensure we don't
duplicate the total cost, ensure we reuse the final shuffle and
recognise that we reduce the total instruction count (so fold even when
NewCost == OldCost, not just NewCost < OldCost).
