River Riddle 56a698510f [mlir][Pass][NFC] Merge OpToOpPassAdaptor and OpToOpPassAdaptorParallel
This moves the threading check to runOnOperation. This produces a much cleaner interface for the adaptor pass, and will allow for the ability to enable/disable threading in a much cleaner way in the future.
