Hi Mads
Can I ask you to take a look at this CL. Soren is out of office same as
Vitaly.
This change modifies ScopeInfo, but is should behave exactly the same until
liveedit is actually used.
I am disposing old stack manipulation code and replace it with a better
one. It
remove 1+ frames, but the bottom (js) frame gets restarted. I add a small
patch
to the code of function and reset the scope on stack. Hope that's enough.

Description:
Reimplement stack manipulations for LiveEdit
Overview:
When function gets updated with a new code, it may stay activated on stack
and
have to be restarted. The code of the function is additionally patched with
a
'restarter' code snippet and PC is set there.
All scope analyzers must realize that there are no local variables in this
state.
