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 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
