Change stack alignment on linux to 16 bytes to keep gcc 4.4 happy.
This fixes the mksnapshot segfault without requiring -fno-tree-vectorize
which just avoided the problem by not generating code with movdqa.

- 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.

The current version is now held in src/version.cc in a number of defines which needs to be modified when changing version.
The following defines make up the version information:
MAJOR_VERSION
MINOR_VERSION
BUILD_NUMBER
PATCH_LEVEL
CANDIDATE_VERSION
The first four are numbers and the fifth is a boolean. Besides these five the define
SONAME
can be used to set a specific soname when building the a shared library (see below). This will most likely be used on stable branches where binary compatibility is ensured between different versions. This define is a string.
This version information is now read by the SCons build to support setting the soname for a Linux shared library. This requires passing the option soname=on to the SCons build.
When soname=on is specified the soname for the shared library can be set in two different ways. Either it will be the full versioned library name (e.g. libv8-1.2.2.so) or a specific soname defined in src/version.cc. Whenever a shared library is build with an soname the filename of the library will hold the full version name (e.g. libv8-1.2.2.so).
I did not update the xcode project with the new files.

ENABLE_DEBUGGER_SUPPORT is enabled by default unless it is on Android platform.
On Android platform, it can also enabled by passing -DENABLE_DEBUGGER_SUPPORT flag to the compiler.
This should not affect any existing build (I hope, cross my fingers) except the build in real Android environment (in other word, it only affects me now).
There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

Turning off Microsoft Visual C++ link-time code generation makes linking on Windows significantly which is convenient during development. There has also been a request from embedders for a way to control this for embedding application which does not use link-time code generation.
The name of the option is msvcltcg and the default value is 'on' to keep the same behaviour as before.

The code has been compiled and tested on Windows, Linux and Mac OS.
The FreeBSD version is a copy of the Linux version which should work on FreeBSD as well. According to the FreeBSD documentation clock_gettime is part of the standard C library so the assumption is that no additional link libraries is required for FreeBSD.

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.

V8 can now be build with MinGW. It still fails the following four tests in debug mode:
mjsunit/parse-int-float
mjsunit/mirror-array.js
mjsunit/integer-to-string.js
mjsunit/regress/regress-114.js
Building with MinGW has been tested with version 5.1.4 using GCC 3.4.5.
In addition to supporting MinGW this change also makes it more explicit which targets needs to link with which libraries.

/GF) in both SCons and Visual Studio build. There is not mesurable difference
neither in speed nor in code size.
Added whole program optimization to the SCons release build. This clutters the
linking of the samples a little with the option /LTCG. This option is not
strictly needed for linking, but if it is not specified the linker complaints
as it can see object files compiled with /GL and then restarts itself with
/LTCG which dosen't look very pretty.

LINKFLAGS take effect. This fixes building shared libraries on 64-bit Linux.
Removed the CCFLAGS from the CXXFLAGS for Linux as SCons combines these
automatically on Linux. This removed the duplication of flags when compiling on
Linux.
On Linux SCons defines CXXCOM as follows
'CXXCOM': '$CXX -o $TARGET -c $CXXFLAGS $CCFLAGS $_CCCOMCOM $SOURCES'
whereas on Windows it is
'CXXCOM': '$CXX $CXXFLAGS $CCCOMFLAGS'

of the case where ENV is not a dictionary which could happen when the
environment variable ENV was set when invoking SCons.
Fixed building dynamic library on Windows in the case where env overrides was
specified as before these was not passed to the linking of the DLL.
There is still a SCons issue when the environment variable ENV is set when
invoking SCons, however this looks like a SCons issue.

- Fixed mozilla test breakage caused by python's obscure module
loading rules.
- Made sure test.py propagates test failures out as the exit code of
the script.
- Remove runtime calls to get number constants. Remove Heap roots for
some special numbers.
- Fix typo in accessors.h.
- Changes CopyMap to not copy descriptors. Adds
CopyMapRemoveTransitions that copies non-transition descriptors.
Changes interface of DescriptorArray::Copy operations to simplify
them.

In the shell sample don't print the result of executing a script, only
evaluating expressions.
Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.

Added a few samples and support for building them. The samples include a simple shell that can be used to benchmark and test V8.
Changed V8::GetVersion to return the version as a string.
Added source for lazily loaded scripts to snapshots and made serialization non-destructive.
Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed).
Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects.
Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events.
Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable.
Improved performance of converting values to condition flags in generated code.
Merged disassembler-{arch} files.
