Linus Groh 83be39c91a LibJS: Handle Proxy with Array target in IsArray() abstract operation ...

This was missing from Value::is_array(), which is equivalent to the
spec's IsArray() abstract operation - it treats a Proxy value with an
Array target object as being an Array.
It can throw, so needs both the global object and an exception check
now.
