libyuv:loongson optimize compare/row/scale/rotate files with mmi.
Currently, libyuv supports MIPS SIMD Arch(MSA),
but libyuv does not supports MultiMedia Instruction(MMI)(such as loongson3a platform).
In order to improve performance of libyuv on loongson3a platform,
this provides optimize 98 functions with mmi.
