The name in question is not necessarily a symbol, so we have to use Equals instead of ==.

36d128d7b8 Reshuffle an if() condition to not depend on an uninitialized value. 
Node::class_id_ contains garbage for newly allocated (FREE) nodes. This patch
changes the code to first test the node state_, then (for non-FREE nodes),
class_id_, and not the other way around.

This does not affect the branch taken (i.e. the current code is correct),
but makes Valgrind and MSan happy.

c203f05474 Delivery logic for Object.observe 
This CL has two parts: the first is the logic itself, whereby each observer callback is assigned
a "priority" number the first time it's passed as an observer to Object.observe(), and that
priority is used to determine the order of delivery.

The second part invokes the above logic as part of the API, when the JS stack winds down to
zero.

Added several tests via the API, as the delivery logic isn't testable from a JS test
(it runs after such a test would exit).

fbc6e0d883 Object.observe: generate change records for indexed properties. 
Details:
- Extend ElementAccessors with GetAttributes method.
- Add HasLocalElement, Get[Local]ElementAttribute methods to JSReceiver/JSObject.
- Otherwise, mirror implementation for named properties.

Cannot correctly handle the cases yet where an accessor is redefined or deleted.

Also fixed handling of object info table.

bd4e114b8e Add code again to allow reclaiming old unexecuted functions. 
When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".

a31889e2de Fix slack tracking when instance prototype changes. 
This fixes a corner case when the instance prototype of a function is
changed while inobject slack tracking is still in progress. This caused
the intial map to be unrelated for functions with the same shared info
and hence the shared construct stub is no longer generic enough to work
for all those functions.

c54fc70f13 Store Object.observe state per-isolate rather than per-context 
This requires adding a new JSObject to the strong root list and populating it from
object-observe.js. The main other change is that we now directly use ObjectHashTable
from JS rather than using WeakMap, since using the latter would end up leaking whichever
Context initialized that observation state.

Added a test via the API showing that different contexts all end up working on the same state.

In more detail:
- Set observation bit for observed objects (and make NormalizedMapCache respect it).
- Mutation of observed objects is always delegated from ICs to runtime.
- Introduce JS runtime function for notifying generated changes.
- Invoke this function in the appropriate places (including some local refactoring).
- Inclusion of oldValue field is not yet implemented, nor element properties.

Also, shortened flag to --harmony-observation.

f3807ca17b Heavy cleanup of the external pointer API. 
Added highly efficient Object::SetAlignedPointerInInternalField and
Object::GetAlignedPointerFromInternalField functions for 2-byte-aligned
pointers. Their non-aligned counterparts Object::GetPointerFromInternalField and
Object::SetPointerInInternalField are now deprecated utility functions.

External is now a true Value again, with New/Value/Cast using a JSObject with an
internal field containing a Foreign. External::Wrap, and External::Unwrap are now
deprecated utility functions.

Added Context::GetEmbedderData and Context::SetEmbedderData. Deprecated
Context::GetData and Context::SetData, these are now only wrappers to access
internal field 0.

Added highly efficient Context::SetAlignedPointerInEmbedderData and
Context::GetAlignedPointerFromEmbedderData functions for 2-byte-aligned
pointers.

This is a refactoring-only CL which simplifies the way we emit combinations of
Smi+map checks.

9de1d40d28 Improve handling of property loads on the proto chain. 
Previously Crankshaft emitted a generic load for these, now we emit a load of a
named field, guarded by a proto chain check.

LCheckPrototypeMaps now returns the holder, which is for free, because it
already had to check its map as the last step, anyway. This is in sync with what
StubCompiler::CheckPrototype does.
