Patch updates :

1. Add mayContainIrreducibleControl() function to the MustExecute.h so it could be used in mayContainUnboundedCycle() function in Attributtor.cpp.
2. Fix mayContainIrreducibleControl() function as the return value was reversed , it was :
  - Return true if Reducible control.
  - Return false if Irreducible control.
3. Minor fixes in docs.
