If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.
The build-time option is off by default. Nothing should change if
it's not enabled.

--raw writes the raw source data to a separate file
--omit allows omitting the source data from the generated files.
The intention is (future) support for having the embedder optionally
store the source data 'blob' and handling it to V8::Initialize, with
the goal of reducing the binary size of V8.
The patch also contains numerous unrelated changes/refactorings in the hope of increasing maintainability. Let me know whether you agree. In particular:
- Remove some unused code.
- Do not overwrite Python built-ins (e.g. the type() function)
- Do not use a string as exception object (no longer supported in python 2.7)
- Add command line argument handling + help text.
- Split logic into:
- PrepareSources - which reads + preprocesses the source files
- BuildMetadata - which takes the prepared sources and generates the data the code template needs.

o Only substitute constant values for full-words and not for
accidental partial matches.
o Keep the order of macros as in macros.py and allow depending on the
previous macros. We used to allow depending on macros that
happened to sort after the current one in the dictionary.

it in regular flat strings that are part of the snapshot.
After this change we don't need libraries-empty.cc any more. In
this change libraries-empty.cc is just a the same as libraries.cc
and the scons build builds it but does not use it. We can move
in stages to a situation where it is not generated at all for all
the build systems that we have.

1418, and 1419 from bleeding_edge until we have a fix
for the crashers we see on the distributed test infra-
structure.
We know that revision 1383 is causing issues, but I
had to revert some of the other recent RegExp changes
in order to get this part out.

This imports a Python version of Douglas Crockford's JSMin. JavaScript files can annotate that they want to be run through the minifier. Currently debug and mirror are minified.
This results in ~12k savings on the final binary size.

Cleaned up ARM version by removing top of stack caching and by introducing push/pop elimination.
Cleaned up the way runtime functions are called to allow runtime calls with no arguments.
Changed Windows build options to make sure that exceptions are disabled and that optimization flags are enabled.
Added first version of Visual Studio project files.

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.
