ce9298029d Implement circular queues for the C++ version of CPU profiler. 
Circular queues serve as a transport for communicating between
VM, stack sampler and analyzer threads. Logging requirements
for VM and stack sampler are completely different, that's why
I introduced two different versions of CQs.

abc0bd46f6 Add initial version of retainers heap profile. 
The profile is taken together with constructors profile. In theory, it
should represent a complete heap graph. However, this takes a lot of memory,
so it is reduced to a more compact, but still useful form. Namely:

 - objects are aggregated by their constructors, except for Array and Object
   instances, that are too hetereogeneous;

 - for Arrays and Objects, initially every instance is concerned, but then
   they are grouped together based on their retainer graph paths similarity (e.g.
   if two objects has the same retainer, they are considered equal);

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.

2b56660a8b Introduce two separate classes of processor detection: 
- TARGET, the architecture we will generate code for.
  This is brought it from the build system.
- HOST, the architecture our C++ compiler is building for.
  This is detected automatically based on compiler defines.

This adds macros for 32 or 64 bit, and cleans up some
include conditionals, etc.

3c2a7bdf21 Add name inference for anonymous functions to facilitate debugging and profiling of JS code. 
Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

For examples of cases where function names can be inferred, see the tests file.

The messages containing the JSON protocol has a RFC-822 like header with a Content-Length field and with the body containing the JSON in UTF-8 encoding.

The D8 shell has option --debugger-agent to start the debugger agent.

All flags are moved out of the specific modules and into flags.defs, with different sections for debug, release, etc. The flag variables are always defined. For example, a debug flag in release mode still exists, but is read only and set to the default value.
