Somebody else pointed out that I probably want to use Valgrind. It seems to have the ability to count instruction counts as well as cache misses [1] [2].

Yup! valgrind is an amazing tool. Just keep in mind that the program itself will be slower when run under valgrind. Its great for debugging, but your benchmarks should be run raw.

And when all else fails, you reach for Intel VTune. :) Which has provided a free community version for a couple years now, I might add.
