Well, it's important for Qt.

The WIP patch I uploaded is just a very first step to make it possible 
to build with v8
without breaking the most basic features. I have just overhacked every 
problematic part
- instead of finding a proper solution to them - to see how many 
dependencies there are
on JSC as quickly as possible. It should be way better before uploaded 
for review.
