Alessandro Di Federico fbca5bba2e Import OSRA and update SET
* Import OSRA
* Improve the SET (aka `JumpTargetFromConstants`) by introducing the
  `OperationsStack` class.
* Review `harvest` logic
* Allow to disable OSRA (along with the sumjump heuristic)
* Take the core of `getNextPC` out of it and move it to `getPC`, a
  function returning both the current and the next PC. Also, fix a bug
  when reaching the beginning of a basic block.
* Detect "reliable" jump targets: a "reliable" jump target is a jump
  target obtained from a store to a PC but it's not a fallthrough jump.
