f0b3d3062d Fix wait interval calculation in ProfLazyMode test.
Also, add a small delay to be sure that all ticks are logged prior to leaving CheckThatProfilerWorks function.

48b4679396 Use uint in ProfLazyMode test when measuring time delta.
While testing ProfLazyMode stability I encountered a situation when the cycle supposed to run for 200 ms started to run "infinitely" because delta between two int64_t values became negative.

e48095b87c Implement a dynamically growing memory log buffer with an upper limit.
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.

e66a0831fd Run script in ProfLazyMode test longer to improve stability.
Prior to this change debug version of the test crashed 2 of 1000 times. After the change no crashes (out of 1000 runs) occured.

62caa393b0 Changed the flags that indicate the status of running vs dead
This allows us to optimized the EnsureInitialized() function
so it doesn't require a function call when we're running

9f69c414eb Implement resource-saving ("lazy") mode of Profiler.
This is intended to be used with Chromium. When in resource-saving mode, profiler doesn't consume any resources (sampler and logging is off) until resumed. Then again, when profiler is paused, sampling and logging are turned off.

Tested under Linux and Windows. Also have done preliminary testing with Chromium.

f76cb020f9 Fix test-log/EquivalenceOfLoggingAndTraversal for the snapshot case.
If was failing because with snapshot the range between minimum and maximum addresses of heap objects is very large (close to 0xf0000000). To fix this I rewrote handling of address maps in the test.

Submitting with TBR because of late time. I think, we'll need to revisit this change tomorrow.

4075179fbe Introduce Logger::LogCompiledFunctions that logs current map of compiled code.
The goal is to make possible having --prof flag always enabled in Chromium.  Currently we can't do this because --prof causes compiler and gc to log code creations / moves / deletes which aren't needed until we start profiling.  With LogCompiledFunctions it will be possible not to log anything until we start profiling.  When started, the current map of compiled functions will be logged and compiler / gc logging will be enabled to update current state.  When profling is stopped, logging will be turned off again.

Funny that testing code is actually much longer and complex than function code.

bf63b8f173 Introduce internal Log class that handles writing log messages, enable logging to memory buffer.
This will enable reading profiler log in Chrome. The current implementation of memory buffer is trivial (fixed size buffer, no memory recycling) but enough to start end-to-end DevTools Profiler implementation. Later it will be enhanced.
