NOTE:
(1) Fixnum's LSB is always 1.
It means you can always run `x - 1` without overflow.
(2) Of course `z = x + (y-1)` may overflow.
Now z's LSB is always 1, and the MSB of true result is also 1.
You can get true result in long as `(1<<63)|(z>>1)`,
and it equals to `(z<<63)|(z>>1)` == `ror(z)`.
GCC and Clang have __builtin_add_ovewflow:

You can see all of code history here:
<https://github.com/vnmakarov/ruby/tree/hash_tables_with_open_addressing>
