libJIT NCI Frame Builder Branch

I alluded to it earlier, but today is the big announcement: Newcomer Peter Lobsinger has developed a patchset to replace Parrot's ad hoc NCI frame builder with a libJIT-based solution instead, and sent it to me as part of my JIT Challenge. Well, today he set up a branch of Parrot on github with the patch for public review. I recommend that all Parrot developers check it out to see what kinds of things are possible in a libJIT-integrated Parrot.
