PPC: remove unnecessary alignment on local variables
Storing a single element from a vector where all elements have the same value does not require an aligned destination. Which element is stored depends on the alignment of the destination address, but since they all have the same value, the result is the same regardless of the alignment. Originally committed as revision 19696 to svn://svn.ffmpeg.org/ffmpeg/trunk
