1cfc63cf8a New heap profiler: implement fast retaining sizes approximation.
Approximation is done by building a dominators tree for the heap graph.
Dominator nodes and retained sizes are serialized into JSON.

Removed:
 - reachable size (it is useless, after all);
 - HeapEntryCalculatedData (size is now stored in the node, retaining
   paths in a hash map);

d46fb9d454 New attempt to make the allocation routines 64 bit clean.
This one has been approved by the 64 bit compiler in MSVC
2005 so I hope it also passes the 2008 version.

The --max-new-space-size option is now in kBytes.
The --max-old-space-size option is now in MBytes.

Some issues remain with 64 bit heaps and the counters.  See

The collector class automatically expands to hold the values added to it,
like a List, but doesn't ensure that the backing store is contiguous, which
allows it to avoid copying back and forth as the buffer grows.

This is in preparation for identifyng identical symbols during preparsing.

ec86513519 Make class BitField able to use 32 bits of a uint32.
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.

This happened when instantiating a bitfield BitField<T, shift, size> with 
[shift=0, size=32] or [shift=31, size=1] or more general any 
[shift=X, size=32-X]

As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

eb4d261e24 Remove the different length string types
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.

On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

8c16bc13bc Implement tick events compression in a log file.
Two techniques are involved:
 - compress repeated line ends (common stack beginnings) by using back references;
 - do RLE compression of repeated tick events.

This gives only 5% size reduction on benchmarks run, but this is because tick events are only comprise 10% of file size. Under Chromium winnings are bigger because long repeated samples of idleness are now compressed into a single line.

Tickprocessor will be updated in the next patch.

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.

94879a93b0 Add a script cache to the debugger
When loaded scripts are requested this cache is filled with all the script objects in the heap. Hereafter its content is kept in sync with the active scripts in the heap through the notifications of new scripts compiled and by using weak handles to get notified when a script is collected.

Through the tracking of collected scripts the debugger event OnScriptCollected have been added to notify a debugger that a script previously returned through the scripts command is no longer in use.

Make the ComputeIntegerHash globally available.

Moved clearing of the mirror cache to when debugger is really left. Previously recursive invocations of the debugger cause the mirror cache to be cleared causing handles to become either stale or reference other objects.

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.

31e7138e1a Improved performance of garbage collection by changing the way we use the marking stack in the event of stack overflow during full garbage collection and by changing the way we mark roots.
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.

769cc962a0 Improved performance of unary addition by avoiding runtime calls.
Fixed the handling of '>' and '<=' to use right-to-left conversion and left-to-right evaluation as specified by ECMA-262.

Fixed a branch elimination bug on the ARM platform where incorrect code was generated because of overly aggressive branch elimination.

Improved performance of code that repeatedly assigns the same function to the same property of different objects with the same map.

Untangled DEBUG and ENABLE_DISASSEMBLER defines.  The disassembler no longer expects DEBUG to be defined.

Added platform-nullos.cc to serve as the basis for new platform implementations.

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.
