    match.pd: Don't create BIT_NOT_EXPRs for COMPLEX_TYPE [PR104675]

    We don't support BIT_{AND,IOR,XOR,NOT}_EXPR on complex types,
    &/|/^ are just rejected for them, and ~ is parsed as CONJ_EXPR.
    So, we should avoid simplifications which turn valid complex type
    expressions into something that will ICE during expansion.
