090647da84 avcodec/mips: [loongson] optimize vp8 decoding in vp8dsp. 
Optimize vp8 loop filter with mmi, four functions optimized:
1. ff_vp8_h_loop_filter8uv_mmi.
2. ff_vp8_v_loop_filter8uv_mmi.
3. ff_vp8_h_loop_filter16_mmi.
4. ff_vp8_v_loop_filter16_mmi.

Vp8 decoding speed improved about 50%(from 73fps to 110fps, Tested on loongson 3A3000).

Constraint "g" means compiler can store variable in memory or register.
When we use constraint "g" for a variable and this variable was operated by
instruction which only support register operands may lead "invalid operands" error.

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
