I'd rather not duplicate this readonly data. I had this clever idea that we'd do something like:

  const Builtin::Info BuiltinInfo[] = {
  ...
  #include "BuiltinsX86_32.def"
  #include "BuiltinsX86.def"
  #include "BuiltinsX86_64.def"
  };

And then our makeArrayRef call would take the appropriate parts.
