If addvsi3 actually performs addvdi3, that will be most surprising to
everyone.  I think that's a very bad idea.  Since we are not invoking
addvsi3, and I suspect it's impossible to convince the compiler to do
so, I think there's no reason to provide the backward compatibility
function at all; the symbol was unused and unusable.
