While I suggested that the change be written like this, I didn't think
long about that specific code, and overall, I really don't think this
change is what should be applied. Though you probably tested that it
allows correct decoding.

I'm for writing a SIMD unaligned loop, the question being whether it
should be the only path. SSE4 version of add_hfyu_left_pred for
instance has 3 paths for various alignments.
