Johannes Goetzfried 7efe407672 crypto: serpent - add x86_64/avx assembler implementation 
This patch adds a x86_64/avx assembler implementation of the Serpent block
cipher. The implementation is very similar to the sse2 implementation and
processes eight blocks in parallel. Because of the new non-destructive three
operand syntax all move-instructions can be removed and therefore a little
performance increase is provided.

Patch has been tested with tcrypt and automated filesystem tests.

Tcrypt benchmark results:

Intel Core i5-2500 CPU (fam:6, model:42, step:7)
