Simplify hash function to a single multiplication
More than likely the compiler will do the three operation breakdown we had here before (2 shifts + subtraction), but let the compiler do the optimizations and make the actual operation more obvious. This actually slightly shrinks the function binary size, likely due to instruction reordering or something. Signed-off-by: Dan McGee <dan@archlinux.org>
