; optnone disables AMDGPUAnnotateUniformValues, so no branch is known
; to be uniform during instruction selection. The custom selection for
; brcond was not checking if the branch was uniform, relying on the
; selection pattern to check that. That would fail, so then the branch
; would fail to select.
