Jussi Kivilinna ddaea7869d crypto: cast5-avx - tune assembler code for more performance 
Patch replaces 'movb' instructions with 'movzbl' to break false register
dependencies, interleaves instructions better for out-of-order scheduling
and merges constant 16-bit rotation with round-key variable rotation.

tcrypt ECB results (128bit key):

Intel Core i5-2450M:

size    old-vs-new      new-vs-generic  old-vs-generic
        enc     dec     enc     dec     enc     dec
256     1.18x   1.18x   2.45x   2.47x   2.08x   2.10x
1k      1.20x   1.20x   2.73x   2.73x   2.28x   2.28x
8k      1.20x   1.19x   2.73x   2.73x   2.28x   2.29x

[v2]
 - Do instruction interleaving another way to avoid adding new FPU<=>CPU
   register moves as these cause performance drop on Bulldozer.
 - Improvements to round-key variable rotation handling.
 - Further interleaving improvements for better out-of-order scheduling.
