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.
