Subject: No more local reduction functions in Reductionops.

This is extracted from #9710, where we need the environment anyway to compute
iota rules on inductive types with let-bindings. The commit is self-contained,
so I think it could go directly in to save me a few rebases.

Furthermore, this is also related to #11707. Assuming we split cbn from the
other reduction machine, this allows to merge the "local" machine with
the general one, since after this PR they will have the same type. One less
reduction machine should make people happy.
