Serialize edge counts instead of indexes in heap snapshot.
...
The serialized node structure currently holds an index
of its first containment edge in the edges array.
The index can be quite big (up to 7 digits for large snapshots).
The patch changes the serialization format to pass
node containment edge count instead. For most nodes the count
is just a single digit number.
This reduces serialized snapshot size and therefore its transfer time.

This allowed the following changes:
- heap profiler now makes one pass less over the heap.
- HeapEntriesMap does not allocate EntryInfo per each entry.
- there's no need for an extra pass to set indexes before serialization.
As a result snapshot taking time has reduced up to 2x times.

Add v8::HeapGraphNode::GetHeapValue method.
...
This allows getting a heap object by a heap snapshot node for further
inspection. Very useful for objects from bindings that mostly have
getter-provided fields.

Rename SmartPointer to SmartArrayPointer.
...
As pointed out in: http://codereview.chromium.org/7754007/#msg5
"SmartPointer should have been named SmartArrayPointer as it expects an input
allocated using new[] and deallocates it using delete[]. Using it as a simple
scoped pointer for a single object is incorrect."

Pick the namespace alias 'i' from v8.h.
...
These files already include v8.h so they don't need to define the
namespace alias again.

Remove the ability to compile without logging and profiling
...
The preprocessor defines ENABLE_LOGGING_AND_PROFILING and ENABLE_VMSTATE_TRACKING has been removed as these where required to be turned on for Crankshaft to work. To re-enable reducing the binary size by leaving out heap and CPU profiler a new set of defines needs to be created.
