Final cleanup for avx2 isolation and consistent file names (#40)

Summary:
Pull Request resolved: https://github.com/pytorch/FBGEMM/pull/40

File name changes + removal of -mavx2 compiler flag non-avx files

This completes the separation of avx2 code to few files that make minimal use of c++ std lib.
