objtool: Add Direction Flag validation
Having DF escape is BAD(tm). Linus; you suggested this one, but since DF really is only used from ASM and the failure case is fairly obvious, do we really need this? OTOH the patch is fairly small and simple, so let's just do this to demonstrate objtool's superior awesomeness.
