Mark primitives integer as able to participate in reductions (fixes #10560).

The documentation states:
- Norm means the term is fully normalized and cannot create a redex
  when substituted
- Cstr means the term is in head normal form and that it can
  create a redex when substituted (i.e. constructor, fix, lambda)
