fa5bc7ea0b Streamline CodeGenerator::Comparison in the IA32 code generator. When
doing constant folding, handle only the cases that actually arise.
This avoids some complicated logic, some extra comparisons, and fixes
issue 247:

9f78714717 Disable the compilation caching for scripts to make it
possible to start generating code specific to a global
object. We should start caching scripts but make the
mechanism local to a specific global context inspired
by the way we handle eval-caching.

92aa4ab36c Add V8 debugger agent.
The debugger agent listens on a TCP/IP port for a remote debugger connection. When such a connection is established the debuger JSON protocol is communicated between the agent the the remote debugger. 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.

3db607a3c4 Dump more stack frames to perf log when executing a C++ function.
JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp.
The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h

StackTraceFrameIterator moved to frames.*

Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks.

I haven't took an advantage of having multiple stack frames in tickprocessor yet.

that an element is mirrored in memory) for elements whose target is a

Changed the debugger events JSON generation to use the same serailizer as the responses to requests. This provides correct serialization of mirror objects in debugger events. Renamed ResponsePacket to ProtocolMessage as it is not only used for responses.

be059966c1 Add socket support to platform code.
The new Socket class is an encapsulation of the standard BSD socket API. As it depends on platform specific include files and have some slight platform variations it is part of the platform code.

On Mac OS only the option SO_REUSEADDR is set to true for server sockets. Running the test required it as the bound listener socket would sometimes end up in TIME_WAIT. On Windows and Linux this has never been observed (given the client end of the socket is closed before the server end).

The code has been tested on Windows, Linux and Mac OS. The FreeBSD version is a copy of the Linux version but has not been compiled nor tested.

Missing Xcode project updates.

the variable could be global we check context extension objects at

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in
