Rollup merge of #150817 - cleanup-inline-const-pat-borrowck, r=lcnr 
cleanup: remove borrowck handling for inline const patterns

rust-lang/rust#120390 added borrow-checking for inline const patterns; a type annotation was added to inline const patterns in the THIR to remember the `DefId` and args of the constants so they could be checked and constraints could be propagated to their parents. As of rust-lang/rust#138499 though, inline const patterns can't be borrow-checked due to a query cycle, and as of rust-lang/rust#149667, the type/`DefId`/args annotations on inline const patterns have been removed, so the borrowck code for them seems unused; this PR removes it.

In a hypothetical future where borrowck doesn't depend on exhaustiveness checking so `inline_const_pat` can be reinstated, I imagine we also won't be evaluating inline const patterns before borrowck. As such, we might be able to reuse the existing code for normal unevaluated inline const operands in [`TypeChecker::visit_operand`](32fe406b5e/compiler/rustc_borrowck/src/type_check/mod.rs (L1720-L1749)) (or at least we shouldn't need to encode inline const patterns' `DefId` and args in user type annotations if they appear directly in the MIR).

README.md

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).
