- Sort ORC entries in the internal table. Older Linux kernels did not sort them in the file (only during boot time).
- Add an option to dump sorted ORC tables (--dump-orc).
- Associate entries in the internal ORC table with a BinaryFunction even when we are not changing the function.
- If the function doesn't have ORC entry at the start, propagate ORC state from a previous entry.
