Andreas Rheinhardt	c00cd007e8	configure: Remove av_restrict All versions of MSVC that support C11 (namely >= v19.27) also support the restrict keyword, therefore av_restrict is no longer necessary since `75697836b1`.

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.

All versions of MSVC that support C11 (namely >= v19.27)
also support the restrict keyword, therefore av_restrict
