Ensure that either this query has all green inputs or been executed. Executing query::ensure(D) is considered a read of the dep-node D.

This function is particularly useful when executing passes for their side-effects -- e.g., in order to report errors for erroneous programs.

Note: The optimization is only available during incr. comp.
