Just a few comments, but looks great otherwise.

This drops dep_graph before linking now, so this should reduce memory consumption during linking.

This is introducing a stall inside what looks kind of like an accessor, when there wasn't one before. I think there should be a comment on the function, at least. Also, double check that this doesn't seem like a problem at any call sites.

Good point, and after a second thought, I think it makes more sense to keep join_codegen in where join_codegen_and_link was, so that behavior changes should be minimized.
I add a commit to the PR moving join_codegen into Linker::link to demonstrate the change, could you take a look?

BTW, we can still drop dep_graph before calling backend to link, so we should reduce similar memory consumption during linking, as if we join codegen inside Queries::linker().
