c5a8743a1b Simplify TurboFan's c1visualizer file handling.
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.

7a70d6a0eb Update intialization of vtune support.
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.

f843327ea0 Cleanups to Verifier.
This CL broadens the checks done by the verifier in untyped mode and introduces some subroutines to shorten the code a bit.

Introduce routines CheckUpperIs() CheckUpperMaybe() and CheckValueInputIs() that are called unconditionally by the verifier. If the typing mode is untyped, then don't check anything.

Also added a couple checks for Merge and Loop nodes that catch bugs where the operator and the node disagree on input counts (a bug encountered today).

37bd114925 Update ObjectToString to Harmony-draft algorithm
Updates Object.prototype.toString() to use algorithm described in harmony drafts.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.
