refactor(library/simplifier): relax rule for conditional equalities
...
The idea is to support conditional equations where the left-hand-side does not contain all theorem arguments, but the missing arguments can be inferred using type inference.
For example, we will be able to have the eta theorem as rewrite rule:
theorem eta {A : TypeU} {B : A → TypeU} (f : ∀ x : A, B x) : (λ x : A, f x) = f
:= funext (λ x : A, refl (f x))

fix(library/elaborator): missing condition
...
The elaborator was failing in the following higher-order constraint
ctx |- (?M a) = (?M b)
This constraint has solution, but the missing condition was making the elaborator to reduce this problem to
ctx |- a = b
That does not have a solution.

fix(kernel/type_checker): is_proposition method was still assuming that a Pi never has type Bool
...
The method is_proposition was using an optimization that became incorrect after we identified Pi and forall.
It was assuming that any Pi expression is not a proposition.
This is not true anymore. Now, (Pi x : A, B) is a proposition if B is a proposition.
