dc91b5f368 Avoid the KMP overhead for simple indexOf() operations. Will look into evaluating the best cutoff between a simple search and KMP in the future. This improves some simple operations ~1.5x.

6f5368146b Don't try an indexOf() when the search string is bigger than the string. The current code will spend a bunch of time trying to match, even though we should know a match is impossible.

968facb9ff - Fixed issue when building samples and cctests on 64-bit machines.
- 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.

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.

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.
