Johannes Doerfert f8ee915deb Use wrapped reduction dependences 
This change will ease the transision to multiple reductions per statement as
  we can now distinguish the effects of multiple reductions in the same
  statement.

  + Wrapped reduction dependences are used to compute privatization dependences
  + Modified test cases to account for the change

Johannes Doerfert f1906138b4 Model statement wise reduction dependences 
+ Collect reduction dependences
+ Introduced TYPE_RED in Dependences.h which can be used to obtain the
  reduction dependences
+ Used TYPE_RED to prevent parallelization while we do not have a privatizing
  code generation
+ Relax the dependences for non-parallel code generation
+ Add privatization dependences to ensure correctness
+ 12 Test cases to check for reduction and privatization dependences
