This is based on Georg's work on typing arithmetic operations (https://codereview.chromium.org/658743002/).

Instead of weakening to bitset types, we weaken to the closest 2^n
limit if we see that we are re-typing a node with a range type (which
means that the node can be part of a cycle, so we might need
to speed up the fixpoint there).

Still having GetTurboCfgFileName in Isolate is ugly, but if we decide that we
don't want to truncate the output file (which would be consistent with
--trace-hydrogen), this could be moved to TurboCfgFile where it actually
belongs.

This speeds up both the case from the bug (using Object.create) but also
takes care ofthe "{ __proto__: obj  }" syntax, which was previously (and
erroneously) being treated the same as setting the prototype dynamically
from script using the __proto__ setter or Object.setPrototypeOf.

 In R23940 (https://code.google.com/p/v8/source/detail?r=23940) it introduces
 Isolate::CreateParams and mentions that V8::SetJitCodeEventHandler should either
 be passed to Isolate::New as well, or invoked via the Isolate.

 When Chrome as embedder of V8, we will set the Jit Code event handler for Vtune
 support during the initialization of renderer process and V8 has be initialized
 at that time. It's better that we invoke V8::SetJitCodeEventHander via the Isolate.
 So we change the vTune::InitializeVtuneForV8(v8::Isolate::CreateParams& params) to
 vTune::InitializeVtuneForV8(v8::Isolate* isolate).

 we will do corresponding changes in chromium code if this patch is landed and Chromium
 updates V8 to the
 new release branch.

 some part of this patch is provided by denis.pravdin@intel.com.
