THIR patterns: Use `ty::Value` in more places throughout `const_to_pat` This PR changes `ConstToPat::valtree_to_pat` to take a `ty::Value` instead of separate type and valtree arguments, and propagates that change throughout other parts of the overall `const_to_pat` implementation. The biggest under-the-hood change is that instead of combining valtrees from the constant with child types from the parent type, we now just rely on the types already embedded in children of the valtree. I'm not *entirely* sure that this is correct, but it doesn't seem to cause any failures in the test suite, and from what I can tell the old way was a holdover from a time when the types weren't readily available from the value side. --- My ulterior motive for this cleanup is that I'm hoping to eventually add some extra data to `thir::PatKind::Const`, which will be a little easier if creation of that `PatKind::Const` doesn't have to assemble a `ty::Value` from component parts. |

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).
