    c: fix uninitialized c_expr::m_decimal [PR106830]

    I added c_expr::m_decimal in r13-2386-gbedfca647a9e9c1a as part of the
    implementation of -Wxor-used-as-pow, but I missed various places where
    the field needed to be initialized.

    Fixed thusly.

            * c-warn.cc (check_for_xor_used_as_pow): Don't try checking
            values that don't fit in uhwi.
