PR tree-optimization/53465
* tree-vrp.c (extract_range_from_cond_expr): First copy_value_range
vr0 into *vr, then vrp_meet that.
(vrp_meet): If one vr type is VR_UNDEFINED, ensure the result doesn't
have any equivalences.
(vrp_visit_phi_node): Call copy_value_range instead of vrp_meet the
first time.

* gcc.c-torture/execute/pr53465.c: New test.
