avcodec/mips: [loongson] reoptimize put and add pixels clamped functions.
Simplify the usage of intermediate variable addr and remove unused variable all64 in following functions: 1. ff_put_pixels_clamped_mmi 2. ff_put_signed_pixels_clamped_mmi 3. ff_add_pixels_clamped_mmi This optimization speed up mpeg4 decode about 2% on loongson platform(tested with 3A3000).
