It turned out that I had missing dialect_resources. program-with-dialect-resources.zip has the missing IR.
During verification of util.global we should probably check if the referenced resource is missing.

util.global private @__constant_tensor_4x6x5x5xf32 {inlining_policy = #util.inline.never, stream.affinity.default = #hal.device.affinity<@__device_0>} = dense_resource<torch_tensor_4_6_5_5_torch.float32> : tensor<4x6x5x5xf32>

Ah yeah, someone hit this the other day when they incorrectly deleted required resources. MLIR should be checking this kind of thing, if anything - resources are an MLIR concept. Globals aren't enough to validate as any op or attribute can reference resources and we can't always be exhaustively checking them all.
