Measure cache line utilization

Question

Is there a way to measure cache line utilization? By cache line utilization I mean the fraction of cache line bytes that are read or written before a cache line is evicted. My target is an Intel CPU running Linux. The measurements don't necessarily need to come from the physical CPU itself. A simulation like valgrind uses is fine too.

The motivation is that this could be a useful way to skim code for areas where changing memory layout is worth considering.
