avcodec/mips: MSA (MIPS-SIMD-Arch) optimizations for AVC intra prediction functions

Browse Source 
This patch adds MSA (MIPS-SIMD-Arch) optimizations for AVC intra prediction functions in new file h264pred_msa.c
Adds new generic macros (needed for this patch) in libavutil/mips/generic_macros_msa.h
