We can just use the existing equate relation for query instantiation. I don't expect us to want to move everything into TypeRelating.

this is now the only NllTypeRelatingDelegate in existance, just stop using a delegate and inline this into the relation? That does require moving the whole relation to rustc_borrowck which... does that cause some privacy issues?

Also... NllNllTypeRelatingDelegate looks horrible 😅 maybe just name the struct `TypeRelatingDelegate' or sth, given that it's in borrowck so clearly for nll

i am in generally in favor of this change

NllNll was a typo, lol

Overall result: no relevant changes - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.
