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.

After this CL all liveedit tests call the same LiveEdit::PatchScript method. This method will be updated later. As well some new liveedit cctests added, unfortunately part of them do not work with current implementation.
