Take outlined function calls/returns into account:

- isCall: true when RD!=X0 (this matches more than just outlined calls but it seems to make sense to treat any JAL/JALR that stores its return address as a call).
- isReturn: True when RS1 is X1 (normal returns) or X5 (returns from outlined functions).
