3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

On ia32, SAHF is guaranteed. It's only necessary to probe for it on x64.

ab3afc5722 Reland "Prevent liveedit on or under generators with open activations" 
The change relative to the previous CL is a logic change in
DropActivationsInActiveThreadImpl.  The previous CL skipped the matcher
unless the frame was a JS frame; this was correct for
MultipleFunctionTarget but not for SingleFrameTarget.

I have not been able to reproduce the original failures on either
architecture (ia32 or x64; stack frame dropping is unsupported on other
architectures).

a7e816db28 Introduce a separate event for CodeDeopt 
The reuse of CodeCreateEvent for deopt events caused a CodeCreateEvent
fired twice for a code object. When the event was processed for the first
time it seized the no-fp-ranges from code object, so the second event
had no ranges info leaving code entry without them.
As a result when a cpu profile sample falls into the region it missed the
2nd stack frame.
