    match.pd: Further complex simplification fixes [PR104675]

    Mark mentioned in the PR further 2 simplifications that also ICE
    with complex types.
    For these, eventually (but IMO GCC 13 materials) we could support it
    for vector types if it would be uniform vector constants.
    Currently integer_pow2p is true only for INTEGER_CSTs and COMPLEX_CSTs
    and we can't use bit_and etc. for complex type.

            Restrict simplifications to INTEGRAL_TYPE_P.
