Log:
        PR tree-optimization/65875
        * tree-vrp.c (update_value_range): If in is_new case setting
        old_vr to VR_VARYING, also set new_vr to it.  Remove
        old_vr->type == VR_VARYING test.
        (vrp_visit_phi_node): Return SSA_PROP_VARYING instead of
        SSA_PROP_INTERESTING if update_value_range returned true,
        but new range is VR_VARYING.

        * gcc.c-torture/compile/pr65875.c: New test.
