e19ed79414 feat(shell/lean): pass environment to and from Lean, remove environment.mk_empty axiom 
/cc @leodemoura

I didn't remove the implementation of `environment.mk_empty`, we may want to use
it in tests.

0b7d987699 feat(frontends/lean, library/init/lean): opaque constants 
@kha I have added support for opaque constants to the old C++ frontend,
and made sure the new frontend can still parse `library/init/core.lean`.
The kernel should enforce that opaque constants are really opaque, and
the following example should fail
```
constant x : nat := 0
theorem foo : x = 0 := rfl
```
If it doesn't, it is a bug.

Here are some remaining issues:
1- `environment.mk_empty` is currently an axiom because we cannot create
an inhabitant of an opaque type. A possible solution is to use
`option environment` instead of `environment`.

2- There is no support for opaque constants in the new
frontend. However, I modified it to handle axioms, and fixed the literal
values with decl_cmd_kind. I tried to mark some of my changes with
comments, but it is probably much easier for you to just check the
commit change list.

3- I did not add any support for automatically constructing `e`
at `constant x : t := e`. I think we can do this later
after we replace the old frontend with the new one. BTW, it took only a
few minutes to provide the inhabitants manually.

They are very similar to `theorems`, but they are never ever unfolded.

ed4cd39d59 feat(library/init/lean/compiler/ir): new IR for Lean 
It is currently implemented in C++. The plan is to move the procedures
for inserting inc/dec, reset/reuse, and inferring borrow inferences to
Lean. Another goal is to make sure new IR optimizations can be
implemented in Lean, and to avoid backend optimizations that would
have to be duplicated in each backend (e.g., `emit_proj_inc_reset_seq`
at `emit_cpp.cpp`).

3f50df70bc perf(library/init/lean/name): use hash code to speedup name.quick_lt 
We use the same trick in the C++ version of this function.

I measured the impact using `lean --new-frontend core.lean` and checking
the number of instructions executed reported by Valgrind.
