      This reverts commit 5253d7bf.
      
      Reason for revert: Elements don't properly invalidate the cache.

      Included mjsunit JavaScript test suite and C++ unit tests. · c42f5829

      In the shell sample don't print the result of executing a script, only
      evaluating expressions.
      
      Fixed issue when building samples on Windows using a shared V8
      library.  Added visibility option on Linux build which makes the
      generated library 18% smaller.
      
      Changed build system to accept multiple build modes in one build and
      generate seperate objects, libraries and executables for each mode.
      
      Removed deferred negation optimization (a * -b => -(a * b)) since this
      visibly changes operand conversion order.
      
      Improved parsing performance by introducing stack guard in preparsing.
      Without a stack guard preparsing always bails out with stack overflow.

      Changed all text files to have native svn:eol-style. · 7276f14c

      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.
