4fa607ec57 Revert unkosher change to xcode project. 
Should have been reverted before committing 5775, but that revert failed to stick.

f386f97476 Move part of scanner.* into scanner-base.* for reuse in preparser scanner. 
Make checks.h not depend on flags.h or global.h (or anything else except
include/v8stdint.h). Only checks.cc has the dependencies (so another
implementation of checks.cc can be provided by the preparser).
Now files depending on checks.h (using ASSERT macros) can include it
directly without depending on all of v8.

decd0fed78 CPU profiler: make code events handling scalable. 
I changed the implementation of a queue between the VM and processor
thread to be unbounded and lock-free, using Herb Sutter's example from
DDJ article: http://www.ddj.com/high-performance-computing/210604448

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.

- 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.

e718576d4f Split handle scopes into an internal version and a version accessible 
through the API. This allows us to verify state on entry through the API.
In this change verification in the API entry is checking that the current
thread holds the V8 lock when a HandleScope is instantiated if a v8::Locker
has ever been used by the V8 instance.
