Merge #8514
8514: Add more profiling spans into type inference r=matklad a=SomeoneToIgnore Fixes https://github.com/rust-analyzer/rust-analyzer/issues/8503 I've added a minimal set of spans to remove `???` and showcase the underlying issue: <img width="1552" alt="image" src="https://user-images.githubusercontent.com/2690773/114722983-f2181900-9d42-11eb-821d-9e93ded5f81f.png"> `db.trait_solve` reliably produces the same timings for the same input in the same place for me, despite supposedly being cached by Salsa. In my perception, this is a bit odd, so I've decided to stop at this point and discuss it with people with better knowledge on the topic. Co-authored-by: Kirill Bulatov <mail4score@gmail.com>
