Partially revert #868 (#878) This commit partially reverts #868 to restore the intrinsics to their original implementation to avoid breaking changes. This is done while rust-lang/rust#73166 is running through crater, and should unblock rust-lang/rust#74482.
This repository contains two main crates:
core_arch implements core::arch - Rust's core library architecture-specific intrinsics, and
std_detect implements std::detect - Rust's standard library run-time CPU feature detection.
The std::simd component now lives in the packed_simd crate.
To do a release of the core_arch and std_detect crates,
dev-dependencies in their Cargo.toml files (due to https://github.com/rust-lang/cargo/issues/4242),
