e8320f4f78 Function::GetScriptOrigin should supply sourceURL when script name is not available. 
GetScriptOrigin is used for DevTools instrumentation.

If inspected call-site is inside "eval" then returned script name is "undefined". To fix this problem we can use the "nameOrSourceURL" method of script-wrapper.

This is a re-upload of https://codereview.appspot.com/6811090/ for the purpose of landing.

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).

- 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".

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.
