Unrolled build for rust-lang#120896

Rollup merge of rust-lang#120896 - compiler-errors:coro-closure-kind, r=oli-obk Print kind of coroutine closure Make sure that we print "async closure" when we have an async closure, rather than calling it generically a ["coroutine-closure"](rust-lang#120361). Fixes rust-lang#120886 r? oli-obk
