Computing the max without `if` statements in Solidity

A frequent operation is determining which of two unsigned integers is greater than the other.

We might typically write this as

We could also do it in one line with `max = x > y ? x : y;`.

However, this introduces a branch at the bytecode level, which increases the gas cost in Solidity.

Using a few clever bit manipulation tricks, we can compute the max without a conditional statement.
