The main issue was due to multiple recompilations of functions. Now code objects are grouped by function using SFI object address. JSFunction objects are no longer tracked, instead we track SFI object moves. To pick a correct code version, we now sample return addresses instead of JSFunction addresses. tools/{linux|mac|windows}-tickprocessor scripts differentiate between code optimization states for the same function (using * and ~ prefixes introduced earlier). DevTools CPU profiler treats all variants of function code as a single function. ll_prof treats each optimized variant as a separate entry, because it can disassemble each one of them. tickprocessor.py not updated -- it is deprecated and will be removed.

It turns out they were filtered out. But when I unfiltered them, I discovered another issue: when DevTools run, regexp literals get recompiled each time they called (looks like this is concerned with switching to full compiler), so I ended up having multiple entries for the same regexp. To fix this, I changed the way of how code entries equivalence is considered.

This simplifies writing tests a lot, because it is now possible to guarantee that certain function will present in a profile by starting profiler from inside it.

As several pages can run in a single V8 instance, it is possible to have functions from different security contexts intermixed in a single CPU profile. To avoid exposing function names from one page to another, filtering is introduced. The basic idea is that instead of capturing return addresses from stack, we're now capturing JSFunction addresses (as we anyway work only with JS stack frames.) Each JSFunction can reach out for context's security token. When providing a profile to a page, the profile is filtered using the security token of caller page. Any functions with different security tokens are filtered out (yes, we only do fast path check for now) and their ticks are attributed to their parents.

The simple formula "ms = ticks * sampler_interval" doesn't work, because e.g. on Linux, the actual sampling rate can be 5 times lower than the one set up in the code. To calculate actual sampling rate, current time is periodically queried and processed along with actual sampling ticks count.

This is to make possible enabling usage of the new profiling subsystem in Chromium without much hassle. The idea is pretty simple: unless the new profiling API is used, all works as usual, as soon as Chromium starts to use the new API, it will work too.
