Arnold Schwaighofer a7ad84851b ARM cost model: Penalize insertelement into D subregisters
Swift has a renaming dependency if we load into D subregisters. We don't have a
way of distinguishing between insertelement operations of values from loads and
other values. Therefore, we are pessimistic for now (The performance problem
showed up in example 14 of gcc-loops).
