topasm: top-level asm is special
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.
