Is it worth adding something like this for the multiplication case as well?

No, multiplication is a pretty fast operation, and the added branches to
test would cause more overhead than what you would save. But, division is a
very slow operation, and I believe that even with the extra branches it
would still help.

If we do this, it should be a separate patch anyway, where we can actual do
measurements to see if there was an improvement, and revert if not.
