benchmarks: add new benchmarks with gcc 7.2 and on NUC E3815

benchmarking: new benchmarks with gcc 6.3. Added edison 64 bits data with edison on linux 4.13 x86_64.

crc32c_test: print identification

CPUDetection: change to standard intrinsics

Makefile: fix flags for Edison x86_64 kernel

Merge pull request #2 from cwlbraa/master

remove dangling submodule

Relocated README to root, fixed rate unit in graph

Imports intel's hand optimized asm code that uses crc32 and pclmulqdq.

Put the crc32q in macros with alternative for 32 bit compilation

Added Adler's CRC32 version (based on Intels) with 3 parallel sections.
