This patch refines the default cost for interleaved load groups having gaps. If a load group has gaps, the legalized instructions corresponding to the unused elements will be dead. Thus, we don't need to account for them in the cost model. Instead, we only need to account for the fraction of legalized loads that will actually be used.
