3c7aae759b Pretenure mode was erroneously consulted in FastCloneShallowObjectStub. 
FastCloneShallowObjectStub is only called from full code. When the code
is optimized, then we'll inline the cloning and respect pretenure mode.

64d2dfa232 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.

84aa5263f3 Remove the last remnants of the TranscendentalCache. 
It was only used for Math.log, and even then only in full code and in %_MathLog. For crankshafted code, Intel already used the FP operations directly, while the ARM/MIPS ports were a bit lazy and simply called the stub. The latter directly call the C library now without any cache. It would be possible to directly generate machine code if somebody has the time, from what I've seen out in the wild it should be only about a dozen instructions.

Object<-->id mapping doesn't depend on a particular snapshot, actually same object may appear in several heap snapshots.

As the next step I'm going to deprecate and remove HeapGraphNode::GetHeapValue.
