Jiaxun Yang	1042039ccd	avcodec/mips: Use MMI marcos to replace Loongson3 instructions ... Loongson3's extention instructions (prefixed with gs) are widely used in our MMI codebase. However, these instructions are not avilable on Loongson-2E/F while MMI code should work on these processors. Previously we introduced mmiutils marcos to provide backward compactbility but newly commited code didn't follow that. In this patch I revised the codebase and converted all these instructions into MMI marcos to get Loongson2 supproted again.

Jin Bo	ebedd26eef	libavcodec/mips: Fix specification of instruction name ... 1.'xor,or,and' to 'pxor,por,pand'. In the case of operating FPR, gcc supports both of them, clang only supports the second type. 2.'dsrl,srl' to 'ssrld,ssrlw'.

gxw	1466dc140d	avcodec/mips: [loongson] optimize theora decoding with mmi. ... Optimize theora decoding with mmi in functions: 1. ff_vp3_idct_add_mmi 2. ff_vp3_idct_put_mmi 3. ff_vp3_idct_dc_add_mmi 4. ff_put_no_rnd_pixels_l2_mmi Theora decoding speed improved about 32%(from 88fps to 116fps, Tested on loongson 3A3000).
