2009-09-27Drop unused args from vector_fmul_add_add, simpify code, and renameMåns Rullgård
The src3 and step arguments to vector_fmul_add_add() are always zero and one, respectively. This removes these arguments from the function, simplifies the code accordingly, and renames the function to better match the new operation. Originally committed as revision 20061 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-08-26dsputil: declare some arrays 16-byte alignedMåns Rullgård
