The other moves in this function pass the result of getPredicate() to the
assembler. Do we need to handle conditional vector moves? We should probably at
least assert that it's an unconditional move in case some higher level code
tries to generate one.

The same can be said for the emit() method. Adding TODO to fix that case as
well!

I talked to John and (at least currently) we shouldn't be generating conditions
for these vector moves.

Done
