Starting in thrust 1.8 the implementation of scan inclusive inside
thrust became highly optimized by using parallel task groups. This
new implementation has a bug that only exists when using custom
binary operators, large size arrays, release mode, and no
debugger or mem-checker attached.

While I have submitted the issue to thrust, we need to be able
to work around the existing issue. The solution I have chosen is
to mark all vtkm::exec::cuda::interal::WrappedBinaryOperators
as being commutative as far as thrust is concerened. To make
sure we don't get any unexpected behavior I have also had
to create WrappedBinaryPredicate so that we don't mark any
predicate as commutative.
