crypto: des_3des - add x86-64 assembly implementation
Patch adds x86_64 assembly implementation of Triple DES EDE cipher algorithm.
Two assembly implementations are provided. First is regular 'one-block at
time' encrypt/decrypt function. Second is 'three-blocks at time' function that
gains performance increase on out-of-order CPUs.
tcrypt test results:
Intel Core i5-4570:
