r57789 (74cdd89) was gradually "improve"d by naruse through r57793 to
r57806, resulted in reverting the efect of r57789 while retaining its
complexity. I think the current situation is slightly worse than
before (same output complicated source code).
Here I introduce __builtin_add_overflow again, which (I think) is what
naruse wanted to do in r57793.

Looking at the source code, FIXABLE tends to be just before LOING2FIX
to check applicability of that operation. Why not try computing first
then check for overflow, which should be optimial.
I also tried the same thing for unsigned types but resulted in slower
execution. It seems RB_POSFIXABLE() is fast enough on modern CPUs.

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)`.
