Remove workaround for old compilers that do not support SSSE3.

We now require SSSE3, SSE4.1, SSE4.2, AVX, F16C, AVX2, and FMA compiler support on x86.  This lone workaround for missing SSSE3 support is incongruous.  It's also unlikely that there's any x86 compiler that supports C++11 but not SSSE3, certainly none we care about.
