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.

[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.

Add map transition for observed objects
This patch enables objects to undergo a single transition when they become observed, avoiding the need to create a new map for every observed objects.
Observed objects which become unobserved does not cause another map transition and unobserved does not clear the observed bit on the map. The unobserved object.

Implement truncated d-to-i as a stub on x86
- Added a general DoubleToIStub so that it's possible to extend to other platforms and non-truncating case.
- This version handles all cases of truncation (previous code deopted in some cases) and all source/destination register combinations without clobbering any temps.
