The build process must add -DCAN_USE_UNALIGNED_ACCESSES=1 to the
C++ flags to activate the support. This is a commit for
Subrato of CodeAurora. See http://codereview.chromium.org/1731013
Small edits by Erik Corry to activate unaligned accesses by
default on the simulator and testing Android builds.

This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

Remove messages.h from v8.h and include it explicitly in only the few places
it is needed. Many files relied on getting handles-inl.h implicitly from
messages.h through v8.h, so include handles-inl.h explicitly in v8.h
instead.
Remove zone-inl.h from header files where it is not needed, can be replaced
by a forward declaration, or can be replaced by zone.h (specifically,
factory.h and heap.h). Include zone.h or zone-inl.h in header files where
it was implicitly included via heap.h or factory.h. Prefer zone.h over
zone-inl.h in header files where possible by including zone-inl.h in .cc
files.

It is now possible to experiment with profiler guided optimizations when building V8. First build an instrumented sample shell:
> scons pgo=instrument sample=shell
Then run the JavaScript code to optimize for using that sample shell. Finally build an optimized sample shell.
> scons pgo=optimize sample=shell
Currently this does not work when building V8 as a DLL due to scons deleting v8.exp prior to the pgo=optimize step.
Due to a bug in Visual Studio (seen in version 2008) the function MessageDispatchHelperThread::Run() in debug.cc needs to be empty for this to work.

The SCons build now has the options profilingsupport and debuggersupport for controlling the setting of the defines ENABLE_LOGGIGN_AND_PROFILING and ENABLE_DEBUGGER_SUPPORT. By default both are set to true.
The changes to the XCode project have not been tested.

The SCons build now supports building for 64-bit Windows. This still requires that the SCons build is passed an env parameter containing the PATH and LIB for the 64-bit build as SCons autodetects the 32-bit environment.
Lowered the warning level for the 64-bit build temporarily.
Added a verbose option to SCons to display the startup banner for the Microsoft Visual C++ tools.

Don't copy the ENV variable from the users's external environment into
construction environments. SCons uses this as a dictionary of environment
values for the commands it executes.
BUG=none
TEST=build with the variable ENV set in the user environment

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.
BUG=151
