I remember it was intented for use in several ACELP codecs like
unfinished G.729, so I think it's better to leave generic version
there (with shift) and use special version for APE (with shifting
thrown out).

In any case, don't forget to comment out AltiVec entries in
libavcodec/ppc/int_altivec.c if needed.
