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.

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'. In the case of operating FPR, gcc
  supports both of them, clang only supports the second type.

They are not properly namespaced and not intended for public use.

df13b75aa1 avcodec/mips: [loongson] reoptimize simple idct with mmi.
Performance of mpeg4 decoding improved about 23%(from 128fps to 158fps, tested on loongson 3A3000).
Reoptimized following functions with mmi.
1. ff_simple_idct_put_8_mmi
2. ff_simple_idct_add_8_mmi
3. ff_simple_idct_8_mmi
