test(tests/lean/run): define brec_on and binduction_on for a reflexive type
...
We say an inductive type T is reflexive if it contains at least one constructor that
takes as an argument a function returning T.
For reflexive types it doesn't seen to be possible to define a single
brec_on that can eliminate to Type.{>=1} and Prop.
The universe level expressions get too complicated.
Even if we extend the universe constraint solver in the kernel, the
additional complexity might be a problem.
We workaround this issue by defining two versions of brec_on:
- One (brec_on) that eliminates to Type.{>=1}, and
- binduction_on that eliminates to Prop.
For non-reflexive types, we can combine both of them.

fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286
...
The problem was that heq type is
Pi {A : Type} (a : A) {B : Type} (b : B), Prop
The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.
The fix is to remove this assumption.
