3b742c5d69 refactor(library/data/real/complete): use 'em' instead of 'decidable.em' 
It is slightly faster since it avoids type class resolution.
It looks more readable too.
Note that em is not axiom anymore. It is a theorem based on choce.

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.

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.

notation + coercions will behave as expected.
