Normalizing method signatures can unify inference variables, which can cause receiver unification to fail. Unify the receivers first to avoid that. Fixes rust-lang#36701. Fixes rust-lang#45801. Fixes rust-lang#45855.

Marking as beta-accepted. Regression, fix looks safe and targeted. |

Unify the receivers first to avoid that. Fixes #36701. Fixes #45801. Fixes #45855. r? @eddyb beta-nominating because #43880 made this ICE happen in more cases (the code in that issue ICEs post-#43880 only, but the unit test here ICEs on all versions).
