    Adjust testcase.
    
    r13-1762-gf9d4c3b45c5ed5f45c8089c990dbd4e181929c3d lower complex type
    move to scalars, but testcase pr23911 is supposed to scan __complex__
    constant which is never available, so adjust testcase to scan
    IMAGPART/REALPART_EXPR constants separately.

            * gcc.dg/pr23911.c: Scan IMAGPART/REALPART_EXPR = ** instead
            of __complex__ since COMPLEX_CST is lower to scalars.
