93445d1617 Replace i by trailing_ones, part of a patch by dark shikari.
No speed change meassureable with START/STOP_TIMER, but this is needed
for future optimizations.

2fd1f0e026 Use the new idct functions (except chroma as it was slower in benchmarks)
cathedral +0.5% speed
aladin +0.6% speed [note aladin has been cat-ed 10 times to reduce the influence
of init time]
Speedup also verified via START/STOP_TIMER (difference was very significant
for the changed parts)
