Based on TOSA's `availability.mlir` test, it seems like they intend to run it with `-mlir-disable-threading` anyway; would it be better to simply have a check like `if (getContext().isMultithreadingEnabled())`, and emit an error if it is?

(I was also working on this issue, and am curious about your perspective).
