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.

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.

[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.

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

Suppress array bounds check for nacl build.

The NaCl and the ARM builder started failing to compile at revision 15593 with spurious array bounds warnings.

The ARM builder will be fixed by updating the cross-compiler version. Since the nacl compiler comes with the nacl toolchain, the warning will be suppressed for that builder.

A new gyp variable 'v8_full_debug' can be set to 0 in order to turn on optimization level 1 for debug builds. With the default (=1), it builds in debug mode like before.

The intention is to run some bots on the waterfall with this configuration. Tests have a x5 speed-up like that.
