Add sse4 if bmi2 is enabled The only change done to the Makefile to get a somewhat faster binary as discussed in #2291 is to add -msse4 to the compile options of the bmi2 build. Since all processors supporting bmi2 also support sse4 this can be done easily. It is a useful step to avoid sending around custom and poorly tested builds. The speedup isn't enough to pass [0,4] but it is roughly 1.15Elo and a LOS of 90%: LLR: -2.95 (-2.94,2.94) [0.00,4.00] Total: 93009 W: 20519 L: 20316 D: 52174 Also rewrite the documentation for the user when using `make --help`, so that the order of architectures for x86-64 has the more performant build one on top.
