Thanks, that's definitely usable, but we'd still need to make sure we
have the right version of Clang.

But since the Clang version is part of the path emitted by
`-resource-dir`, maybe it's easier to just get it from there.

So as long as it's a reasonable assumption that a matching Clang is on
the path, we can just invoke them and do a best match on the version
part of the resource dir.
