Enable zlib in LLVM on aarch64-apple-darwin
Works on macOS 13.4, Xcode version 14.3.1.0.1.1683849156
This was disabled in #75500 on Apple Silicon Developer Transition Kit, but Apple appears to have fixed their zlib now

This will be needed to create synthetic targets in future commits.

rust-lld is not located in the same directory as the other binaries that
point to ../lib, but in a deeper directory in lib. So we need to point
a few layers up for rust-lld to find the LLVM shared library without
rustup's LD_LIBRARY_PATH overrides.

Adds support for LLVM [SafeStack] which provides backward edge control
flow protection by separating the stack into two parts: data which is
only accessed in provable safe ways is allocated on the normal stack
(the "safe stack") and all other data is placed in a separate allocation
(the "unsafe stack").
SafeStack support is enabled by passing `-Zsanitizer=safestack`.

Initial support for loongarch64-unknown-linux-gnu
Hi, We hope to add a new port in rust for LoongArch.
LoongArch intro
LoongArch is a RISC style ISA which is independently designed by Loongson
Technology in China. It is divided into two versions, the 32-bit version (LA32)
and the 64-bit version (LA64). LA64 applications have application-level
backward binary compatibility with LA32 applications. LoongArch is composed of
a basic part (Loongson Base) and an expanded part. The expansion part includes
Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD
EXtension (LSX) and Loongson Advanced SIMD EXtension(LASX).
Currently the LA464 processor core supports LoongArch ISA and the Loongson
3A5000 processor integrates 4 64-bit LA464 cores. LA464 is a four-issue 64-bit
high-performance processor core. It can be used as a single core for high-end
embedded and desktop applications, or as a basic processor core to form an
on-chip multi-core system for server and high-performance machine applications.

Since last year, we have locally adapted two versions of rust, rust1.41 and rust1.57, and completed the test locally.
I'm not sure if I'm submitting all the patches at once, so I split up the patches and here's one of the commits

FreeBSD 13.1 and 13.2 can build Rust with LLD just fine on powerpc.

- `aarch64-unknown-linux-ohos`
- `armv7-unknown-linux-ohos`

Renamed 'native.rs' to 'llvm.rs', also moved `TestHelpers` to `test.rs`.Replaced all the `native.rs` ocurrences at `src/bootstrap` files to `llvm.rs`
