Mention issues with integer owerflow for random number generators.
This mentions the issues with integer overflow and how to work
around them.
it's basically fine, although I'd prefer a formulation replacing

by something like:
GCC 13 includes new optimizations which may change behavior on
integer overflow. Traditional code, like linear congruential
pseudo-random number generators in old programs and relying on a
specific, non-standard behavior may now generate unexpected results.
In such cases it is recommended to use the intrinsic ...
Thanks for updating the documentation!
