I completely agree, it's possible to do some tracing of what the V8 JIT does, but the workflow is awful.
Microbenchmarks don't represent the real world. Instead of running a single microbenchmark, I suggest running a host of them, but all of them "at the same time" (not serially). They'll get in each others ways and total performance will be far worse.
This happens with AOT code as well of course, because caches are being trampled no matter what, but JIT code only exarcerbates the issue because it is larger.
