Approx 10% speedup in cook on files tested: Remove some inner loops in favour of memcpy/memset/vect_add calls; remove multiplication from index arithmetic in loops in favour of pointer arithmetic; make use of the MULT31, MULT31_SHIFT15 and CLIP_TO_15 implementations from codelib instead of having their own implementations in cook
