Top-level ASM statements are parsed as fake anonymous functions. Obviously, they have few in common with functions (for example, they don't have a return type) and mixing the two makes things more complicated than needed (for example, to detect a top-level ASM, we had to check that the corresponding symbol (name) had a null ident). Avoid potential problems by special casing them and return early in linearize_fn(). As consequence, they now don't have anymore an OP_ENTRY as first instructions and can be detected by testing ep->entry. Note: It would be more logical to catch them even erlier, in linearize_symbol() but they also need an entrypoint and an active BB so that we can generate the single statement.
