This change adds the bpfel-unknown-none and bpfeb-unknown-none targets which can be used to generate little endian and big endian BPF
Both cg_llvm and cg_clif don't override it. cg_spirv does override it, so it needs to be preserved.
…k(kind = "raw-dylib")]. This does not yet support #[link_name] attributes on functions, the #[link_ordinal] attribute, #[link(kind = "raw-dylib")] on extern blocks in bin crates, or stdcall functions on 32-bit x86.
BPF target support This adds `bpfel-unknown-none` and `bpfeb-unknown-none`, two new no_std targets that generate little and big endian BPF. The approach taken is very similar to the cuda target, where `TargetOptions::obj_is_bitcode` is enabled and code generation is done by the linker. I added the targets to `dist-various-2`. There are [some tests](https://github.com/alessandrod/bpf-linker/tree/main/tests/assembly) in bpf-linker and I'm planning to add more. Those are currently not ran as part of rust CI.
…enkov Partial support for raw-dylib linkage First cut of functionality for issue rust-lang#58713: add support for `#[link(kind = "raw-dylib")]` on `extern` blocks in lib crates compiled to .rlib files. Does not yet support `#[link_name]` attributes on functions, or the `#[link_ordinal]` attribute, or `#[link(kind = "raw-dylib")]` on `extern` blocks in bin crates; I intend to publish subsequent PRs to fill those gaps. It's also not yet clear whether this works for functions in `extern "stdcall"` blocks; I also intend to investigate that shortly and make any necessary changes as a follow-on PR. This implementation calls out to an LLVM function to construct the actual `.idata` sections as temporary `.lib` files on disk and then links those into the generated .rlib.
Driver improvements This PR contains a couple of cleanups for the driver and a few small improvements for the custom codegen backend interface. It also implements `--version` and `-Cpasses=list` support for custom codegen backends.

Unify duplicate linker_and_flavor methods in rustc_codegen_{cranelift,ssa}.
The two methods were exactly the same so this removes the cranelift copy. This will help make sure both they don't get out of sync.

This has a fix for a miscompilation on AArch64 cc rust-lang#1184
The information is stored in used_crate_source too anyway

…jorn3 Sync rustc_codegen_cranelift The main hightlight this sync is basic support for AArch64. Most things should work on Linux, but there does seem to be an ABI incompatibility causing proc-macros to crash, see rust-lang/rustc_codegen_cranelift#1184. Thanks to `@afonso360` for implementing all Cranelift features that were necessary to compile for AArch64 using cg_clif. Also thanks to `@shamatar` for implementing the `llvm.x86.addcarry.64` and `llvm.x86.subborrow.64` llvm intrinsics used by num-bigint (rust-lang/rustc_codegen_cranelift#1178) and `@eggyal` for implementing multi-threading support for the lazy jit mode.
