Nit: I would suggest adding a `genDispatchClauses` function to the "Code generation functions for clauses" section of this file where you create a `ClauseProcessor` and call `processTODO` on it with the full list of clauses that apply to `!$omp dispatch`, instead of making this check directly here.

That's the general pattern we follow for the other directives and would make it easier to progressively start adding support for clauses over time.
