Can you please move this call into v8::VTuneInitializer::InitializeVTune(),
everybody who calls InitializeVTune will need it and it will go away for all
clients when you support relocation, so it should be hidden in
InitializeVTune().

+    v8::VTuneInitilizer::initilizeVtune();

Spelling: Initializer. Please capitalize all method names, e.g.
"InitializeVTune()" rather than "initilizeVtune".
