43f1708f8b - Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm 
sure it works ok. Also it's slow, so use it only when you _really_ need to
measure quality.
- Fix libavcodec Makefile to enable profiling.

d6a4c0b111 * some modifications to allow gcc to compile same code for -fPIC 
- introduced MOVQ_WONE, MOVQ_WTWO
* unrolled put_pixels_clamped_mmx
* added .baling where the jump address would be compiled on odd address
* added some testing code to disable all these routines (for time measurement)
