Moving more build-pass tests to check-pass One or two tests became build-pass without the FIXME because they really needed build-pass (were failing without it). Helps with #62277 2020-04-19 19:27:28 -05:00			`//@ check-pass`
Refactor async fn return type lowering async fn now lowers directly to an existential type declaration rather than reusing the `impl Trait` return type lowering. As part of this, it lowers all argument-position elided lifetimes using the in-band-lifetimes machinery, creating fresh parameter names for each of them, using each lifetime parameter as a generic argument to the generated existential type. This doesn't currently successfully allow multiple argument-position elided lifetimes since `existential type` doesn't yet support multiple lifetimes where neither outlive the other. This requires a separate fix. 2019-03-13 19:42:23 -05:00			`//@ edition:2018`
