    match: extend the `((a CMP b) ? c : 0) | ((a CMP' b) ? d : 0)` patterns=
 to
support ^ and + [PR103660]

    r13-4620-g4d9db4bdd458 Added a few patterns and some of them can be
extended to support XOR and PLUS.
    This extends the patterns to support XOR and PLUS instead of just IOR.

    Bootstrapped and tested on x86_64-linux-gnu.
