96d13fe62b Micro-profiling assisted "optimization" for Power6. Essentially it's so 
to say educational commit. Reordering instructions doesn't improve
performance much, rather exhibits Power6 limitations.

22c268e6c9 Next generation aes-586.pl featuring AES_[en|de]crypt, accessing exclusively

af8c1d81a3 Reimplement outer rounds as "compact" in x86 assembler. This has rather 
strong impact on decrypt performance, 20-25%. One probably should consider
switching between slower and faster routines depending on how much data
we were asked to process.

985e4c4154 Mitigate the hazard of cache-collision timing attack on last round. The 
only chance for T[ed]4 to get evicted in this module is when its cache
"overlaps" with last 128 bits of key schedule.

9598fa8759 Mitigate the hazard of cache-collision timing attack on last round. Well,

c8d5c71af5 Mitigate cache-timing attack in CBC mode. This is done by implementing 
compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
