e067d82ab3 fix(library/compiler/llnf): nasty bug at explicit_rc_fn 
@kha I found this nasty bug today after I tried a small modification
at lean.parser.token. It is crazy that it didn't manifest itself before.

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.

7051099997 fix(runtime/object): performance bug 
The "quick" filter `&s1 != &s2` was incorrect.
It was actually always false, since it just comparing the stack address
of `s1` and `s2`.
I incorporated the quick filter into `string_eq`.

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

9cc41c4f3d chore(frontends/lean/inductive_cmds): disable broken check 
@kha I have disabled this check. It was implemented 2 years ago by
Daniel, and I don't want to fix it. It seems you have already fixed a
bug there. AFAICT, this check is just for improving error messages.
I believe we may not even need it since the kernel now supports nested
inductive types. AFAIR, Daniel implemented this check here because the
inductive compiler was introducing a lot of auxiliary declarations
that were making the kernel error messages unreadable.

67d197a2e0 fix(runtime/object): correct support for objects without RC 
Lean was not crashing because we do not have region objects yet, and
the persistent objects still have a RC.

778e7e41f9 refactor(library/init/data/rbmap/basic): pass ins node-cell to balance1 and balance2. 
The idea is to reuse the cell. The trick is like the one we used for
improving state_t. It seems to work pretty well. Now, the Lean
version is 29% slower than the C++ one.

ac9e37ed86 feat(library/compiler/llnf): we postpone the simplification of 1-reachable and all-eq cases_on expressions 
Reason: the `cases_on`-expressions are used to guide
`insert_reset_reuse_fn`. The new `simp_cases` simplifier applies the
1-reachable and all-eq cases_on expression simplifications after
`insert_reset_reuse_fn` is executed.
