This change is needed for being able to use different thread indices types without changing Fetchs. Basically decoupling those two areas. 1. This commit removes concrete specialization instantiations of ThreadIndicesTypes in all of the Fetch's specializations. 2. It also moves the ThreadIndicesType template parameter from the Fetch struct to a template parameter in their methods Load/Store.
