add evocative examples for `BitOr` and `BitXor`

These are exactly equivalent to PR #35809, with one caveat: I do not believe there is a non-bitwise binary XOR operator in Rust, so here it's expressed as `(a || b) && !(a && b)`.

Alternative decompositions are `(a && !b) || (!a && b)` and `(a || b) && (!a || !b)`.  Let me know if you think one of those would be clearer.

r? @GuillaumeGomez
