Updated V8 from git://github.com/v8/v8.git to 57f8959fb264354ba1a2e5118db512f588917061

Update V8 source to version 3.10.1.

* Added optimizations and stability improvements on all platforms.
* Various performance improvements.
* Cleanup ScopeInfo and SerializedScopeInfo.
* Introduce extended mode.
* Implemented performance improvements to the incremental garbage
  collector.
* Fixed handling of arrays in DefineOwnProperty. (issue 1756)
* Fixed GCC 4.7 warnings.
* Performance improvements for large Smi-only arrays.
* Reduce the space used by the stack for the profiling thread.
* Reduced memory use immediately after starting V8.
* Fixed VFP detection through compiler defines. (issue 1996)
* Remove static initializers in v8. (issue 1859)
* Optimized boot-up memory use.
* Optimized regular expressions.
