For a description of the issue at hand see this PR: https://github.com/iree-org/iree/pull/20430. This issue tracks a fix for the underlying issue requiring a workaround that necessitated the workaround. The fix will likely need to be in upstream LLVM.

This came up because it would be nice to create a generic tileProducersAndFuseConsumers method upstream, but it would probably be good to fix this workaround first: https://github.com/iree-org/iree/pull/21009#issuecomment-2964315189

I think it is better to close the issue when we truly address it in IREE. E.g., remove the war flags from the codebase.
