e206fcc1af perf(kernel/type_checker): reduce the overhead of creating delayed_justification objects, a huge number of them is created when type checking applications
We reduce the cost by avoiding the allocation of std::functional objects, and the unnecessary increment/decrement of reference counters.

1b4c9f63ce perf(kernel/environment): improve is_descendant performance, optimize for the common case: the is_descendant tree is huge but has few deep branches
This is an important optimization for module.cpp. The benchmark tests/lua/slow/mod2.lua is a good example where the cost of is_descendant was neutralizing the benefit of the replace method.

7b15e558a2 refactor(kernel/converter): implement eta in whnf instead of is_def_eq.
Without cumulativity, we do not have problems with Eta at whnf anymore.
When we had cumulativity, we could not not simply reduce
     (fun x : A, f x) ==> f
This step is correct only if domain(f) was definitionally equal to f.
Here is a problematic example for systems with cumulativity
Given, f : Type.{2} -> Bool
     (fun x : Type.{1}, f x)

4842ae4fc7 refactor(kernel): store macro arguments in the macro_expr
Before this commit, we "stored" macro arguments using applications.
This representation had some issues. Suppose we use [m a] to denote a macro
application. In the old representation, ([m a] b) and [m a b] would have
the same representation. Another problem is that some procedures (e.g., type inference)
would not have a clean implementation.
