Andreas Rheinhardt 8327828205 avcodec/mips/mpegvideo: Set denoise_dct only for encoder
The C version is set in ff_dct_encode_init(), yet the MIPS version
is set in dct_init() (in ff_mpv_common_init() and therefore also
for decoders). This commit fixes this inconsistency.

Jin Bo fd5fd48659 libavcodec/mips: Fix build errors reported by clang
Clang is more strict on the type of asm operands, float or double
type variable should use constraint 'f', integer variable should
use constraint 'r'.

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

Zhou Xiaoyong 89ec4adad6 avcodec/mips: loongson optimize mmi load and store operators
1.MMI_ load/store macros are defined in libavutil/mips/mmiutils.h
2.Replace some unnecessary unaligned access with aligned operator
3.The MMI_ load/store is compatible with cpu loongson2e/2f which not support instructions start with gs

Zhou Xiaoyong a20646bb24 avcodec/mips/mpegvideo_mmi: Version 2 of the optimizations for loongson mmi
1. no longer use the register names directly and optimized code format
2. to be compatible with O32, specify type of address variable with mips_reg and handle the address variable with PTR_ operator

Diego Biurrun 0bf184e59c Move PS2 MMI code below the mips subdirectory, where it belongs.
Also give a more suitable name to the MMI-optimized IDCT;
it is not PS2-specific, as the name currently suggests.
