Rollup merge of rust-lang#117686 - compiler-errors:gen-body, r=wesleywiser

Build pre-coroutine-transform coroutine body on error

I was accidentally building the post-transform coroutine body, rather than the pre-transform coroutine body. There's no pinning expected here yet, and the return type isn't yet transformed into `CoroutineState`.

Fixes rust-lang#117670
