7c0cc3111a fix(kernel/type_checker): we must use different caches for infer_type and check 
The new test tc4.lua exposes the problem being fixed.
We need separate caches otherwise we may mistakenly assume that an expression was already checked by the type checker, while only its type was inferred.

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)
