Rollup merge of rust-lang#129847 - compiler-errors:async-cycle, r=davidtwco Do not call query to compute coroutine layout for synthetic body of async closure There is code in the MIR validator that attempts to prevent query cycles when inlining a coroutine into itself, and will use the coroutine layout directly from the body when it detects that's the same coroutine as the one that's being validated. After rust-lang#128506, this logic didn't take into account the fact that the coroutine def id will differ if it's the "by-move body" of an async closure. This PR implements that. Fixes rust-lang#129811

Don't call closure_by_move_body_def_id on FnOnce async closures in MIR validation Refactors the check in rust-lang#129847 to not unncessarily call the `closure_by_move_body_def_id` query for async closures that don't *need* a by-move body. Fixes rust-lang#130167
