That gives ~20% for dom benchmark/Document Object String Get, speeds up overall
dom_perf (not dramatically) and overall score for peacekeeper.  Strange, but DOM

My assumption that log initialization happens somewhere near the stack's bottom is true for V8's sample shell but isn't true for Chromium, causing many otherwise valid stack addresses to be thrown out. The solution proposed is to save stack pointer value for the outermost JS function in ThreadLocalTop similar to c_entry_fp.

Implemented only for IA-32. Currently I'm not dealing with profiling on ARM and x86-64 anyway.

Change the handling of the debug break stack guard. The debug break is no longer ignored when hit inside "system" JavaScript. The reason for this is twofold:

* Running "system" JavaScript with the debug break flag active leads to slow running code while waiting for the break in non "system" JavaScript (one exception to this it is to try to avoid breaks in the clear mirror cache JavaScript code called when leaving the debugger).

* If this happens while processing RegExp running in native code an infinite loop is created as the stack guard handler for RegExp does not move execution forward

Fixed a GC bug in the interrupt handling for RegExp running in native code.

Added test of debug break while in debug message handler callback and debug break while executing a RegExp.

When profiler's memory buffer is filled up, profiling is stopped and it is ensured that the last record in the buffer is "profiler,\"pause\"" thus making the end of profiling session explicit. Otherwise DevTools Profiler would need to guess whether the current profiling session has been stopped.

I suggest that the lack of initialization causes issue 358 to happen. In Profiler::Disengage an empty TickSample is inserted in order to wake up the Profiler thread. Issue reporter claims that crash happens in LogTickEvent function. My guess is that frames_couint receives a wild value.

The goal of this change is to allow longer profiling sessions and preserve memory when profiler isn't started. The buffer starts with 64K and grows until it reaches the upper limit, which is currently set to 50MB --- according to my evaluations, this is enough for at least 20 minutes of GMail profiling. As we're planning to introduce compression for the profiler log, this time boundary will be significantly increased soon.

To make possible unit testing of the new component, I've factored out Logger's utility classes into a separate source file: log-utils.h/cc. Log and LogMessageBuilder are moved there from log.cc without any semantical changes.
