avcodec/mips: [loongson] optimize put_hevc_qpel_hv_8 with mmi.
Optimize put_hevc_qpel_hv_8 with mmi in the case width=4/8/12/16/24/32/48/64. This optimization improved HEVC decoding performance 11%(1.81x to 2.01x, tested on loongson 3A3000). Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
