[dpdk-dev] [PATCH v3] Implement memcmp using SIMD intrinsics

[Ravi Kerur]

Background:
After preliminary discussion with John (Zhihong) and Tim from Intel it was
decided that it would be beneficial to use AVX/SSE intrinsics for memcmp
similar to memcpy that had been implemeneted. In addition, we decided to use
librte_hash as a test candidate to test both functionality and performance.

Further discussions lead to complete functionality implementation of memory
comparison and v3 code reflects that.

Test was conducted on Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, Ubuntu 14.04,
x86_64, 16GB DDR3 system.
