Port SIMON64 to Altivec
...
SIMON64 runs about 4x faster than C++ for POWER4 and friends. If POWER7 is available it goes back to full speed due to efficient unaligned loads

Move SIMON-64 and SPECK-64 to Power7 minimum
...
SIMON-64 and SPECK-64 don't use 64-bit type so they can run on Power7. We may be able to drop to Power4, but we need to test the effects of Loads and Stores without vec_vxs_ld and vec_vsx_st

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...
