Improve async detection mechanism with blacklist...

Improve async detection mechanism with blacklist Because the async repl works by wrapping any code that raises SyntaxError in an async function and trying to execute it again, cell bodies that are invalid at the top level but valid in functions and methods (e.g. return and yield statements) currently allow executing invalid code. This patch blacklists return and yield statements outside of a function or method to restore the proper SyntaxError behavior.
