Use "d" suffix for general-purpose registers used with movd. This increases compatibilty with nasm and is also more consistent, e.g. with h264_intrapred.asm and h264_chromamc.asm that already do it that way. Originally committed as revision 25042 to svn://svn.ffmpeg.org/ffmpeg/trunk

Move VP3 IDCT functions from inline ASM to YASM. This fixes part of the VP3/5/6 issues on Win64. Originally committed as revision 24988 to svn://svn.ffmpeg.org/ffmpeg/trunk
