For example, you have 2 patches A and B, and B dependent on A. Then you can send the patch A to `llvm-project`'s branch (https://llvm.org/docs/GitHub.html#branches) instead of your repo and open a PR to merge the branch-of-A to main, then you can open another patch for B too and open a PR to merge the branch-of-B to branch-of-A.
