LibJS: Don't VERIFY that a function is Regular when executing in AST

Browse source 
By replacing this VERIFY with a thrown Error we no longer crash when
calling a generator function in the AST interpreter. This allows us to
more gracefully handle situation which have not been implemented yet.
In particular this helps the libjs-test262-runner since it can now
continue on to the next tests instead of having the entire process end.
