; Check that distinct nodes are emitted before uniqued nodes, even if that
; breaks post-order traversals.

; Nodes in this testcase are numbered to match how they are referenced in
; bitcode.  !1 is referenced as opN=1.

; Note: named metadata nodes are not cannot reference null so their operands
; are numbered off-by-one.
