Thank you so much for doing this and the incredible turnaround time! 
I don't have any complaints regardings LLVM Dialect/opaque pointer usage and I am happy to see that the PR ends up being more red than green :slightly_smiling_face:
 
I am not really qualified to comment on Flang specifics things so I'll leave this to other reviewers.
I did leave two comments about things that confused me as a flang outsider that I am curious about whether it is correct or whether I am simply missing some required context.
