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.

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.

This adds a getter for "size" to Set.prototype and Map.prototype which reflects
the number of elements in the Set and Map respectively.

b80cbd7922 Object.observe: generate change records for named properties. 
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.

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.
