Develop a microbenchmark harness that would make it easy to write and run tests.
Created attachment 63125 [details] Patch
This is not yet ready for review, just a general direction of where I am going with it. The idea is to write a simple postMessage-based harness that could be used to run microbenchmarks: separately, together, or as part of the build cycle. Most of the plumbing is in place. Missing are UI, collecting and aggregating stats.
Simon, et al., as I mentioned in #webkit yesterday, I dusted off some old code and made sure it works in WebKit/Gecko/IE/Opera. I'll keep working on it if y'all like where this is going.
