If my understanding is correct, there needs to be some assembly code to setup the JITStackFrame before we call this. How and where is this supposed to be handled?

Since MSVC supports inline assembly only for x86, you need to create an additional assembly file.
http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/create_jit_stubs might be a good staring point.
http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/PlatformWinCE.cmake shows how the script is called.
