The program is essentially broken as is. You can't pass the 'AttrVal' in as a
parameter. At least not yet. This is how you should do that:

  Attributes::Builder B;
  B.addAttribute(Attributes::ZExt);
  F->addAttribute(1, Attributes::get(B));

I'm thinking of adding a helper c'tor to the Attributes class though that could
support the original code, since this is a common enough idiom...But it's not
there just yet.
