Rollup merge of #152218 - adwinwhite:fix-mir-borrowck-opaque-handling-keep-all-errors, r=lcnr

Report unconstrained region in hidden types lazily

Fixes https://github.com/rust-lang/trait-system-refactor-initiative/issues/264

I didn't copy the mechanism of HIR typeck as I found that we just need to be lax in the unconstrained region case.
It already ignores non-defining uses and invalid params.

About tests, I'm having trouble coming up with more complex ones. 🙁

This fixes `ukanren` and `codecrafters-redis-rust` but not rust-lang/rust#151322 and rust-lang/rust#151323.
I believe they are a [different problem](https://github.com/rust-lang/rust/issues/151322#issuecomment-3864656974).

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).

Quick Start
