97681be4e5 Fix data race in SamplingCircularQueue 
This change fixes data race described in the bug by adding Acquire_Load to SamplingCircularQueue::StartDequeue and Acquire_Store to SamplingCircularQueue::Enqueue.

Also the queue implementation imposed a constraint on the records it stored: the first AtomicWord in each record was a marker. For that purpose TickSampleEventRecord had filter field of type int. This approach is error prone, e.g. on x64 sizeof(AtomicWord) is 8 while sizeof(int) is 4. Moreover the queue needs such marker only at the beginning of chunk. I changed the queue so that it stores the marker explicitly as the first Cell in chunk and removed the filter field.

b951f03cee Fixed type feedback in presence of negative lookups. 
To fix the issue at hand regarding constant function calls and perhaps
other hidden issues regarding negative lookups, we basically add a
"marker instruction", just for harvesting purposes. Our type feedback
oracle is really, really fragile, we should better switch to some more
explicit and robust scheme soon.

7632a311aa Some tests involving AllocationSites are failing in GcStress test mode. 
The reason is that an AllocationMemento associated with an array only
lives for one gc (it is unrooted). So an excess of garbage collections
in these tests cause the Memento to be lost, and expected behavior
can't be guaranteed.

a72b5d6c4d Fix invalid array length check in TransitionElementsKindStub. 
The stub used to check the length of the JS array to see if
there's a need to duplicate the elements backing store. This
way it will not duplicate the elements array when going from
double to object even if the elements array is not the empty
fixed array. Later on it will then store pointers into a
FixedDoubleArray.

The native code stub used to check whether elements points to
the empty_fixed_array singleton instead of testing the length.
The Hydrogen stub does that as well now.

11a38ed875 Throw if first argument to TypedArray.set is a number. 
Further refinement to semantics that I have missed in previous change.
Both Blink and Firefox are permissive with arguments to .set method.
However, when first argument to "set" is a number, all implementations
throw, so that users know that
   a.set(0,27)
does not assign 27 to 0th element of a, not 0 to 27th element of a.

fab9f4e126 [Object.observe] Lazily allocate callbackInfo structure 
This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred.

When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state.

---
Note: Naming confusion resolved:

This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map).

This patch resolves this confusion:

"object" (objectInfo, objectInfoMap): This refers to the observed object and its structures

"callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered

"observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list.

35052bc2ea Reland deprecation of HAllocateObject in favor of HAllocate. 
This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.

c65f4f7f7b Don't use StoreIC_ArrayLength on frozen arrays 
The code previously assumed that an array with fast properties must have
a writable length property. But Object.freeze() now exposes a way to make
length read-only without moving the object into slow mode. This patch
simply adds a !is_frozen check to the IC code. Any future optimizations
to attribute-setting on JSArrays will need to make similar accomodations.

487a61934f Improve test-cpu-profiler.cc tests stability 
The tests sometimes fail on bots as they don't have time to collect enough samples. This change makes them use counter of samples taken when v8 is either in JS or EXTERNAL state and repeat sampling until desired threshold is reached.

5b70a58ad2 Fix plot script. 
The script for the time line plot has been broken since r15484, which
changed the format of tick entries in v8.log.

To prevent this from happening in the future, I added a test case.
