Alexey Kozyatinskiy 3dfaf8264f [debug] liveedit in native 
Liveedit step-by-step:
1. calculate diff between old source and new source,
2. map function literals from old source to new source,
3. create new script for new_source,
4. mark literals with changed code as changed, all others as unchanged,
5. check that for changed literals there are no:
  - running generators in the heap,
  - non droppable frames (e.g. running generator) above them on stack.
6. mark the bottom most frame with changed function as scheduled for
   restart if any.
7. for unchanged functions:
  - deoptimize,
  - remove from cache,
  - update source positions,
  - move to new script,
  - reset feedback information and preparsed scope information if any,
  - replace any sfi in constant pool with changed one if any.
8. for changed functions:
  - deoptimize
  - remove from cache,
  - reset feedback information,
  - update all links from js functions to old shared with new one.
9. swap scripts.
