bors 59d4114b2d Auto merge of #129176 - EnzymeAD:enzyme-backend, r=albertlarsan68
Autodiff Upstreaming - enzyme backend

Tracking issue: https://github.com/rust-lang/rust/issues/124509

Part of https://github.com/rust-lang/rust/pull/129175

This PR should allow building Enzyme from source on Tier 1 targets (when also building LLVM), except MSVC.
It's only a small fraction (~200 lines) of the whole upstream PR, but due to bootstrapping and the number of configurations in which rustc can be build I assume that this will be the hardest to merge, so I'm starting with it.
Happy to hear what changes are required to be able to upstream this code.

**Content:**
It contains a new configure flag `--enable-llvm-enzyme`, and will build the new Enzyme submodule when it is set.

**Discussion:**
Apparently Rust CI isn't able to clone repositories outside the rust-lang org? At least I'm seeing this error in CI:
```
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
```
Does that mean we would need to mirror github.com/EnzymeAD/Enzyme in rust-lang, until LLVM upgrades Enzyme from an Incubator project to something that ships as part of the monorepo?

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 integrate 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).
