Limit the number of transitions allowed per hidden class.
...
Each time a transition is added to a hidden class, the whole
transitions array must be copied, which causes poor performance
in some circumstances. This change limits the maximum size of
the transition array, avoiding this behavior in the pathological
case. For example, this improves the performance of the EtchMark
benchmark by nearly 60%.

Narrow cases where Sparse/Smart versions of Array methods are used
...
Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.
Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.
These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.
Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.
This patch depends on https://codereview.chromium.org/666883009 , which
better-aligns the behavior of SmartMove with SimpleMove.

Change SmartMove no-op behavior to match SimpleMove (and ES6 spec)
...
The previous behavior, which caused Array.prototype.unshift() (with no args)
to have side-effects, no longer matches the spec (ES6 changed the no-arg behavior
in April 2014). The new SmartMove behavior is also compatible with current
versions of Firefox.
This is a baby step towards getting rid of SmartMove; it isolates the test
change in this patch, instead of lumping it in confusingly with all the
other test updates necessary for moving away from SmartMove.

[turbofan] Use range types to type and lower arithmetic ops.
...
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).

Fix {get,set}ter-on-elements tests to run through all creation functions
...
setter-on-elements had the wrong length hardcoded in a for loop over the
creation functions (getter-on-elements had the right length, but seemed
worth future-proofing).

Add Terminate operator.
...
Terminate is need for non-terminating loops (NTLs) that can appear after optimizing control flow. It gathers the control and effect(s) from a NTL and connects them to end so that they are not dead-code removed.

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 .

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).

Remove [[PROTOTYPE]] from ObjectToStringHarmony
...
harmony-tostring needs to emulate InstallFunctions --- InstallFunctions will fail
in Debug builds because the `toString` property already exists in Object.prototype.
The fix is to add some of the other features from InstallFunctions() to the
setup of ObjectToStringHarmony.
