question about AltiVec builtins

No, me innocent :-)

Zem's AltiVec rewrite changed vec_dst to use __tern_args_eq instead of 
__un_args_eq.  See

http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/rs6000/altivec.h.diff ?
r1=1.27&r2=1.28&f=h

To find the exact spot, search for dssall, it is near there.

I'd noticed this too when working on my AltiVec rewrite, but forgot to ask the 
list about it.
