Introduce API to temporarily interrupt long running JavaScript code.
It is different from termination API as interrupted JavaScript will continue to execute normally when registered InterruptCallback returns.
/**
* Request V8 to interrupt long running JavaScript code and invoke
* the given |callback| passing the given |data| to it. After |callback|
* returns control will be returned to the JavaScript code.
* At any given moment V8 can remember only a single callback for the very
* last interrupt request.
* Can be called from another thread without acquiring a |Locker|.
* Registered |callback| must not reenter interrupted Isolate.
*/
void RequestInterrupt(InterruptCallback callback, void* data);
/**
* Clear interrupt request created by |RequestInterrupt|.
* Can be called from another thread without acquiring a |Locker|.
*/
void ClearInterrupt();
Fix Hydrogen SCE pass to avoid eliminating stack guards too aggressively. Only normal JavaScript functions are guaranteed to have stack guard in the prologue. If function is a builtin or has a custom call IC it will lack one.
Changes from r18363:
- includes r18364 to fix compilation errors: removes debugging only code;
- makes interrupiton related tests not threaded, because they rely on having exclusive access to the V8 instance and the fact that they can only interrupt themselves, if they are interrupted from the outside they break;
- changes HasStackCheck predicate used during SCE pass to avoid handles dereference to make SCE compatible with parallel recompilation.

All methods for accessing collected profiles by index are deprecated. The indexed storage may well be implemented by the embedder should he need it. CpuProfiler's responsibility is just to create CpuProfile object that contains all collected data and whose lifetime can be managed by the embedder.

Up till now, external strings may be tracked in the string table
(for internalized strings) or the external string table, depending
on in which order internalize and externalize happened.
The internalized string table should not have to deal with external
strings, all of which should be tracked by the external string table.

Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.
Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.
Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.
drive-by: fixed use after free in src/factory.cc

The test in question (test-debug/LiveEditEnabled) is expected to fail, and it
failed, but because of the wrong reason (the test asserts that the default
isolate is not initialized, SetLiveEditEnabled initialized the default
isolate because it doesn't get one as param). Now it fails because of the right
reason.

Heap allocation reported to AllocationTracker may be later divided into several objects so it is incorrect to put the block as a new HeapObject into the map. We will match allocated block with actual HeapObjects later when iterating Heap (will be addressed in another patch). Since the objects are not assigned an id immediately after creation we need to call FindOrAddEntry when finding id for SharedFunctionInfo during stack crawling.
Removed hooks for tracking creation of AllocationMemento. AllocationMemento is not a HeapObject and should be considered as implementation overhead.
Renamed NewObjectEvent to AllocationEvent which is more precise in case of folded allocations and when a part of the new block becomes AllocationMemento.
