Leonardo de Moura edd5e97045 feat(frontends/lean/elaborator): coercion from (decidable) Prop to bool
This is a hard coded extra case. It is not an instance of has_coe.
Even if we change has_coe to accomodate this case, it will not be a
satisfactory solution because this coercion depends on the element and
not the type, and the element usually contains metavariables.

We should eventually write a tactic for synthesizing coercions.
