3ab0e07ba9 feat(frontends/lean): add simp tactic frontend stub 
This commit also removes the fake_simplifier. It doesn't work anymore
because simp is now a reserved word.

f8d472c9f1 feat(frontends/lean/parse_rewrite_tactic): change the semantics of rewrite[↑f] when f is recursive 
After this commit it behaves like 'unfold f'.
That is, it will unfold f even if it fails to fold recursive
applications. Now, only 'esimp[f]' will not unfold f-applications when
it cannot fold the recursive applications.

This commit also closes #692. It is part of a series of commits that
addresses this issue.

a9515ac7a4 feat(library/tactic/rewrite_tactic): try to fold nested recursive applications after unfolding a recursive function 
See issue #692.
The implementation still has some rough spots.
It is not clear what the right semantic is.
Moreover, the folds in e_closure could not be eliminated automatically.

1b414d36e7 refactor(library/init): define prod as an inductive datatype 
Motivation: prod is used internally in the definitional package.
If we define prod as a structure, then Lean will tag pr1 and pr2 as
projections. This creates problems when we add special support for
projections in the elaborator. The heuristics avoid some case-splits
that are currently performed, and without them some files break.
