This patch is to enable the vtune profiling tool support in chrome.

The V8 project provides the support of vtune profiling tool so that the
JavaScript code can be profiled. The initialization of vtune support in
the embedder of V8 is needed.

This patch has the following change:
1, enable the vtune support if "chromium_enable_vtunejit_for_v8" is
enabled before generating the project file. 

2, Add one flag "enable-vtune-support" to enable it for every render
   process. The initialization is invoked in the render process delegate.
   currently linux and windows platform is supported.
