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.
