[benchmarks] GSoC report

Hi again This is another report of my work. I've mostly been looking for a solution for memory handling in the benchmarks project and found out that the smaps-sampling solution used by the "unladen shadow" google project was a good solution, but not optimal. It would have been better to have a solution that also worked for windows, but I could not find anyone that could do it in a good and proper way. I've submitted these diff's for reviews (Have anyone really seen them?). I've also included a cachegrind usage function with some additional parsing code from Paul. Since the last review I've also added some more benchmarks such as Whirl ans j4p5 along with some other minor fixes. I've recently started on the v8-crypto benchmark to convert it from JS and it's a lot of lines, but hopefully it will work without any huge problems. Best regards Alexander
