2020-01-17Rollup merge of #68195 - estebank:impl-trait-2000, r=CentrilDylan DPC-0/+9
Account for common `impl Trait`/`dyn Trait` return type errors - When all return paths have the same type, suggest `impl Trait`. - When all return paths implement the expected `trait`, suggest `Box<dyn Trait>` and mention using an `enum`. - When multiple different types are returned and `impl Trait` is expected, extend the explanation. - When return type is `impl Trait` and the return paths do not implement `Trait`, point at the returned values. - Split `src/librustc/traits/error_reporting.rs` into multiple files to keep size under control. Fix #68110, cc #66523.

2020-01-16Rollup merge of #68096 - varkor:diagnostic-cleanup, r=CentrilDylan DPC-6/+6
Clean up some diagnostics by making them more consistent In general: - Diagnostic should start with a lowercase letter. - Diagnostics should not end with a full stop. - Ellipses contain three dots. - Backticks should encode Rust code. I also reworded a couple of messages to make them read more clearly. It might be sensible to create a style guide for diagnostics, so these informal conventions are written down somewhere, after which we could audit the existing diagnostics. r? @Centril
