the DC coefficients. This has a greater probability of leveraging the 
coefficients while they are still cached.

When testing with the Big Buck Bunny 1080p video, I consistently saw 
improvements of 500k-600k dezicycles per run (through 
reverse_dc_prediction()) thanks to this move.

This is mainly to avoid test failures due to implementation-defined
behaviour of qsort when elements are equal, giving different results
for each of FreeBSD, Linux/glibc and Solaris.
In addition it is about 35 % faster, effect on overall speed is minimal
though (< 2%).
Regression tests are unchanged (i.e. identical to Linux/glibc).
