cq- because we can also remove these unused mirrors of these shifts that I had missed in this cleanup:

llint/LowLevelInterpreter.asm
373:const AtomNumberShift = 3
374:const BitMapWordShift = 4

I would have used class for this, since it has private data members.

Also, why not use functions and lambdas instead of this VoidFunctor thing?

> Source/JavaScriptCore/heap/MarkedSpace.cpp:31
> +    Free(MarkedSpace* space) : m_markedSpace(space) { }

I think this should take a reference, not a pointer.

> Source/JavaScriptCore/heap/MarkedSpace.cpp:34
>      MarkedSpace* m_markedSpace;

I think this should be a reference, not a pointer.

I would have used class for this, since it has private data members.

> +    MarkedSpace* m_markedSpace;

I think this should be a reference, not a pointer.

I think this is so the forEach* methods don't need multiple versions, one for a void return value (lambdas) and one where there are return values.
