avcodec/mips: [loongson] reoptimize simple idct with mmi.
Performance of mpeg4 decoding improved about 23%(from 128fps to 158fps, tested on loongson 3A3000). Reoptimized following functions with mmi. 1. ff_simple_idct_put_8_mmi 2. ff_simple_idct_add_8_mmi 3. ff_simple_idct_8_mmi Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
