subotac opened PR #14030 from subotac:fix/loongarch64-stackswitch-reserve-first to bytecodealliance:main:

Fixes #13885.

Decrement the LoongArch64 fiber stack pointer before saving callee-saved registers, then address each save within the reserved 0xa0-byte frame. This avoids writing below the current stack pointer before the frame is
allocated and matches the existing restore layout.

## Testing

- cargo check -p wasmtime-internal-fiber --target loongarch64-unknown-linux-gnu
- cargo clippy -p wasmtime-internal-fiber --target loongarch64-unknown-linux-gnu -- -D warnings
- cargo fmt --manifest-path crates/fiber/Cargo.toml -- --check
