If a flag along the lines of "--target=sse4,avx-x2" is provided on the command-line, then the program will be compiled for each of the given targets, with a separate output file generated for each one. Further, an output file with dispatch functions that check the current system's CPU and then chooses the best available variant is also created. Issue #11.
