Dylan DPC f1412a665f Rollup merge of #101614 - compiler-errors:rpitit-eq, r=jackh726 ... Equate fn outputs when inferring RPITIT hidden types When we are trying to infer the hidden types for RPITITs, we need to equate the output tys instead of just subtyping them. For example: ```rust trait Foo { fn bar() -> impl Sized {} } impl Foo for () { fn bar() -> &'static str { "" } } ``` If we just subtype the signatures `fn() -> &'static str <: fn() -> _#1t` (where `_#1t` is the variable we've used to infer `impl Sized`), we'll end up `&'static str <: _#1t`, which causes us to infer `_#1t = #'_#2r str`, where `'_#2r` is unconstrained, which gets fixed up to `ReEmpty`, and which is certainly not what we want. I can't actually think of a way to make this fail to compile, because during borrowck we've already done the method probe, and so we just look at the `impl` method signature and see the `&'static str` any time we call `<() as Foo>::bar()`. But this _does_ cause the ICE [here](https://github.com/rust-lang/rust/pull/98559#issuecomment-1241891994) in `@jackh726's` "Remove ReEmpty" PR (#98559) to stop ICEing, because after that PR we were leaking unconstrained region variables into the typeck results. r? types		2022-09-10 18:56:08 +05:30
