This commit changes reducers to use a new object for holding results, namely ReducerElement. This new object either holds a value directly or holds an optional value. The latter is used for identityless reductions to allow cases where the user functors did not write a value into the given reducer and as such the reducer's value should be discounted. This new element is used inside reductions that support identityless to correctly propagate potentially missing values throughout. Signed-off-by: Larsen, Steffen <steffen.larsen@intel.com>
