db2e3727a6 feat(library/type_context): add yet another approximation to unifier 
@avigad I decided to fallback into first-order unification to address
the (a ∉ []) issue.

@dselsam Have you experienced similar problems in the ICML project?
The new comment at type_context.cpp explains the problem and hack to
workaround it. The issue is yet another instance where using "first-order
unification" produces imprecision, but generates the solution we want.

1cfef1c6d9 fix(frontends/lean/parser): save next_inst_idx in the parser snapshot 
This fixes issues with anonymous instances in sections.
In Emacs, we would get spurious error messages such as:

   invalid parameter/variable declaration, '_inst_1' has already been declared

This commit also adds a regression test for the problem.

692701c5ef feat(library/init/meta): use cheap "reflexivity" after simp and rewrite 
The idea is to make sure lean doesn't timeout (at reflexivity) when we apply simp or
rewrite in goals such as

    (x y : nat) |- x + y + 10000000000 = x + y + 200000000000000
