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.

462f6be930 MIPS: The gc should be able to traverse all AllocationSites for decision making. 
Port r15715 (2e830d4)

Original commit message:
The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include:

* Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions.
* The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization.

Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.

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.

10615aef7b AllocationSites: when updating allocation site transition information, 
be careful to merge feedback appropriately. For example, one array may
have gone holey, and then another allocated at the same place instead
went DOUBLE but remained packed. In this case the ElementsKind
ultimately stored in the AllocationSite should be HOLEY_DOUBLE.

On windows, this triggers the dll to be copied to the correct
locations. On other platforms, icudata is compiled in, and depending on
it results in an invalid linker archive ordering.
