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

2c7fd0e36b avcodec/mips/h264qpel_mmi.c: 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
3. use uld and mtc1 to workaround cpu 3A2000 gslwlc1 bug (gslwlc1 instruction extension bug in O32 ABI)
4. h264qpel use hepldsp optimizations
