Rollup merge of #68301 - tmandry:dont-propagate-test-invoke, r=alexcrichton 
Don't propagate __RUST_TEST_INVOKE to subprocess

When -Z panic_abort_tests is enabled, we use an environment variable to
tell the subprocess which test to invoke. If that subprocess then
invokes another Rust test binary, chaos ensues.

Rollup merge of #68195 - estebank:impl-trait-2000, r=Centril 
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.

8cacf50563 Auto merge of #66716 - derekdreery:debug_non_exhaustive, r=dtolnay 
Implement `DebugStruct::non_exhaustive`.

This patch adds a function (finish_non_exhaustive) to add ellipsis before the closing brace when formatting using `DebugStruct`.

 ## Example

 ```rust
 #![feature(debug_non_exhaustive)]
 use std::fmt;

 struct Bar {
     bar: i32,
     hidden: f32,
 }

 impl fmt::Debug for Bar {
     fn fmt(&self, fmt: &mut fmt::Formatter<'_>) -> fmt::Result {
         fmt.debug_struct("Bar")
            .field("bar", &self.bar)
            .non_exhaustive(true) // Show that some other field(s) exist.
            .finish()
     }
 }

 assert_eq!(
     format!("{:?}", Bar { bar: 10, hidden: 1.0 }),
     "Bar { bar: 10, .. }",
 );
 ```
