This attempts to address http://llvm.org/bugs/show_bug.cgi?id=18220 It also fixes a test which was requiring the *wrong* output. I'm relatively happy with this part, and it even solves most of the hard part of feature request for .code16 in bug 8684 — which was actually why I started prodding at this. But I could do with some help with the 16-bit signed relocation handling, which I've
