test: rename backend=stage2 to backend=selfhosted, and add backend=auto
backend=auto (now the default if backend is omitted) means to let the compiler
pick whatever backend it wants as the default. This is important for platforms
where we don't yet have a self-hosted backend, such as loongarch64.

Also purge a bunch of redundant target=native.
