Re-add Simon and Speck, enable SSE (GH #585 )
...
This commit re-adds Simon and Speck. The commit includes C++, SSSE3 and SSE4. NEON, Aarch32 and Aarch64 are disabled at the moment.

Remove Simon and Speck ciphers (GH #585 )
...
We recently learned our Simon and Speck implementation was wrong. The removal will stop harm until we can loop back and fix the issue.
The issue is, the paper, the test vectors and the ref-impl do not align. Each produces slightly different result. We followed the test vectors but they turned out to be wrong for the ciphers.
We have one kernel test vector but we don't have a working implementation to observe it to fix our implementation. Ugh...
