f9dc709c72 - Add a "#error Unsupported target architecture." where needed. A chain of
platform dependent ifdefs is useless if it does not include an error like
  this. You will end up searching for the failure in all the wrong places.

2d7d89d831 Get rid of the notion of "parameter pointer" that no longer exists in
the implementation but still lives on in comments and identifier
names.

Where it was used, it has been changed to "caller's stack pointer".

94a122296d Cleanup of ARM exception handlers. Remove the unused code and
parameter pointer slots.  Change it so that the handler address no
longer points into the middle of the handler.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

2b56660a8b Introduce two separate classes of processor detection:
- 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.

ea56336518 Create build structure for X64.
Possible to attempt to build for X64.
Build will be unsuccessful, since all x64 source files are
missing and pointers are reinterpreted as integers everywhere.

0eb4dea12d Implemented "no heap access" mode for JSFrame which is used for stack sampling in profiler.
As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app.

49af176623 Add another check in profiler's stack iterator to ensure stability.
I made a test run of benchmarks and found another weak point. After
fixing it, benchmarks are able to run for a 100 times in a row
successfully in both builds.

3bd4c93d07 Support profiler stack sampling in any situation. After this change, almost all profiler ticks (except GC ones) have a stack sample data associated.

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.

7276f14ca7 Changed all text files to have native svn:eol-style.
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.
