Almost cosmetic changes in dsputil_init_ppc and vorbis_inverse_coupling_altivec:
- whitespace consistency 2->4 [dsputil_init_ppc] - reorder struct initialization with dsputil_init_altivec [dsputil_init_ppc] - use casts instead of temp variables [vorbis_inverse_coupling_altivec] Originally committed as revision 5918 to svn://svn.ffmpeg.org/ffmpeg/trunk
