Rollup merge of #143125 - tgross35:aarch64-neon-llvm19-f16, r=cuviper 
Disable f16 on Aarch64 without neon for llvm < 20.1.1

This check was added unconditionally in c51b229140 ("Disable f16 on Aarch64 without `neon`") and reverted in 4a8d35709e ("Revert "Disable `f16` on Aarch64 without `neon`"") since it did not fail in Rust's build. However, it is still possible to hit this crash if using LLVM 19 built with assertions, so disable the type conditionally based on version here.

Note that for these builds, a similar patch is needed in the build script for `compiler-builtins` since it does not yet use `cfg(target_has_reliable_f16)` (hopefully to be resolved in the near future).

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).

Quick Start
