  2. codec: add ssse3_atom 

    By performing benchmarks on Intel Edison (a Silvermont Atom CPU) in x86_64 mode
from v0.3.0 we find that SSE3 had  various ups and down. Substantial changes
since v0.3.0 were:
HASH	SSSE3	SSSE3
e12e3cd	165	210
3f3f31c	206	150
67ee3fd	205	205
0a69845	145	205
a5b6739	145	218
6310c1f	157	218
9a0d1b2	158	210
5874921	165	210
Best performance was from 67ee3fd until decode performance regressed
from 205 to 145 MB/s with commit 0a69845. The commit before that
(b6417f3) had best decode performance with relatively good encode.
Core(-i7) processors do not should such large performance changes.
This patch adds the ssse3 codec from b6417f3 as ssse3_atom.
