Original Issue: https://codereview.chromium.org/29353003/

Note that this version of the patch includes logic for bailing out of compiled ArrayPush/ArrayPop calls if the array is observed (see stub-cache-*)

cec8383cff Provide private symbols through internal APIs 
Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes.

On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros:

  NEW_PRIVATE(print_name)
  HAS_PRIVATE(obj, sym)
  GET_PRIVATE(obj, sym)
  SET_PRIVATE(obj, sym, val)
  DELETE_PRIVATE(obj, sym)

In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object.

These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.

92bd4d1f2d I found this working on 
https://codereview.chromium.org/19541010/

The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this).

Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy.

It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy.

Both issues are now fixed and properly tested.

throw, so that users know that

f7ba3a7bb1 Fix stack frame reconstruction for generators with formal arguments 
The formal parameter count was always being treated as an untagged
integer, but it is actually a Smi on ia32 and arm.

d73dace0f5 Delegating yield does not re-box result objects 
Delegating yield (yield*) should just pass on the iterator results it
receives instead of re-boxing them.

cc27c4c41b GeneratorFunction() makes generator instances 
The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances.  This commit implements that
behavior.  It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.

5760c7b598 Disable --harmony -> --harmony-generators implication 
A GC-related bug has started showing up after r15060 that unfortunately
I haven't been able to reproduce.  Disable generators by default for the
Canary push.

f88bca9576 Generator object "next" method takes optional send value 
Update the generators implementation to make "next" also do the job of
what was previously called "send" by taking an optional argument.
Remove send, and do a bunch of renamings.

cb0d146862 Add initial parser support for harmony iteration 
This commit adds initial parser support for harmony iteration.
Specifically, it will parse:

  for (x of y) {}
  for (let x of y) {}
  for (var x of y) {}

The semantics are still unimplemented.

09c489ea93 Re-land: Implement ObservedArrayPop, ObservedArrayShift, ObservedArrayUnshift & ObservedArraySplice 
Original issue: https://codereview.chromium.org/15331002/

Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.

IsObserved now checks for JSReceiver and returns false rather than crashing.
