SSSE3/SSE4/AVX 9-way fully merged i8x8 analysis (sa8d_x9)
x86_64 only for now, due to register requirements (like sa8d_x3).

i8x8 analysis cycles (per partition):
 penryn sandybridge bulldozer
616->600  482->374  418->356  preset=faster
892->632  725->387  598->373  preset=medium
948->650  789->409  673->383  preset=slower
