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.

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".

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 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.
