ffmpeg/libavcodec/mips/vp3dsp_idct_msa.c
gxw a3e572d96f avutil/mips: refine msa macros CLIP_*. 
Changing details as following:
1. Remove the local variable 'out_m' in 'CLIP_SH' and store the result in
   source vector.
2. Refine the implementation of macro 'CLIP_SH_0_255' and 'CLIP_SW_0_255'.
   Performance of VP8 decoding has speed up about 1.1%(from 7.03x to 7.11x).
   Performance of H264 decoding has speed up about 0.5%(from 4.35x to 4.37x).
   Performance of Theora decoding has speed up about 0.7%(from 5.79x to 5.83x).
3. Remove redundant macro 'CLIP_SH/Wn_0_255_MAX_SATU' and use 'CLIP_SH/Wn_0_255'
   instead, because there are no difference in the effect of this two macros.
