Revised patch in progress

Here's a new version of the patch. It runs most tests in the JSC test suite,
but it still segfaults on the odd one, which perhaps means that there is a
reference to the old ActivationImp lying around that I missed. I also
frequently get the error:

ERROR: free is not supported
(/Users/Cameron/WebKit/JavaScriptCore/kjs/CollectorHeapIntrospector.h:56 static
void KJS::CollectorHeapIntrospector::zoneFree(malloc_zone_t*, void*))

However, this is probably due to the destructor automatically being called on
the ActivationImp that is a member of StackActivation.

I think this patch is pretty close to being completely functional. When it is,
we'll just need to make the right segmented stack data structure so we can get
some performance out of it.
