I don't point to the AS spec, as that is not public afaik.  The (public)
book III however says that 2-arg is mandatory (for 32-bit, as well);
however, I see the PEM disagrees.

Let's make either one- or two-arg acceptable for tlbie; however, 
_please_
get the change for cmp[l][i] back in.

Btw, where did problems for tlbie show up?
