We are using __builtin calls in some of our bit manipulation functions. The idea is that the compiler will turn the builtin calls to native instructions, when compiled with the appropriate target flag. There are some indications that this is not always the case

I have quickly checked our rank function's asm with objdump and it looks good; but we should do a deeper dive here.
