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.

066b0fcdf9 feat(library): clean up "sorry"s in library 
Breaking changes: pnat was redefined to use subtype instead of a custom inductive type, which affects the notation for pnat 2 and 3

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.

cf574d0127 feat(library): assign priorities to notation declarations in the standard library 
Now, even if the user opens the namespaces in the "wrong" order, the
notation + coercions will behave as expected.
