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.

98e0eac76f Speed up creation of Objects whose prototype has dictionary elements 
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).

Branch can now have an optional hint, when the condition is
likely true or false, and if such a hint is present the other
basic block will be marked as deferred and placed at the end

We currently use this feature for tagging int32/uint32 in
change lowering, and for load/store bounds checks in simplified
lowering.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures

Symbol.toStringTag is exposed publicly.

8330178b4c The issue is that by handling strings with map/handler pairs instead of a special 
version of the keyed load stub (https://code.google.com/p/v8/source/detail?r=24661),
I allowed polymorphism between string and non-string types in the IC. Before, the
IC would go generic.

Then, at crankshaft time, we special case when we only saw strings. The error
here is that crankshaft can't emit code that handles polymorphism between string
and non-string types. The choice is either to get that to happen (I don't deem
this necessary from a performance point of view, an IC with such type feedback
before would have gone generic), or simply check for the case of "polymorphic
with some string maps" and require crankshaft to go generic. I'll do the latter.
