Moved SSE2 code to separated file to allow using different compiler flags on GCC To use SSE2 in GCC, a compiler -msse2 flag is needed. It adds both possibility to write SSE2 code in the file, but also allows compiles to optimize the whole file with SSE2. To make sure that the code works on non-SSE2 machines, moving SSE2 functions to separated file and compiling only that file with -msse2 is the common practice.
