Fix for HostPrefixSum

In this commit we moved from _mm_extract_epi32 to _mm_storeu_si32. This was done because SSE2 is available in all x86_64 processors, whereas SSE4 is not.
When compiling with gcc9 (Ubuntu OS) the _mm_storeu_si32 is not recognized, see here. HostPrefixSum.cpp has been changed to use _mm_store_ss instead.
