This means you now have to install the high level code grade in order to
bootstrap, but you never use it for anything except passing this test.

In theory it would be better to just test that the compiler accepts the
--high-level-code option, not that you can actually link something
with it.

Using --high-level-code --compile-to-c would probably be enough.

I don't know whether this is worth fixing, but it just bit me so it
might be worth people knowing about.
