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.

f650a1b873 refactor(library/init/meta): avoid '_core' idiom using default parameters 
I kept a few core methods (e.g., exact_core and apply_core). Reason:
if we use default parameters

    meta constant exact (e : expr) (md := semireducible) : tactic unit

then, we will not be able to write

    to_expr p >>= exact

The workaround is

    do t <- to_expr p, exact t

or
    to_expr p >>= (fun x, exact x)

One alternative is to change how we handle default parameters, and
eta-expand applications that involve default parameters.
We may also have an attribute [eta_expand]. Then

    attribute [eta_expand] foo

instructs the elaborator to automatically eta-expand foo-applications.
The attribute would give users more control, and avoid potential
performance problems. Without the attribute, then for every function
application the elaborator has to check the type and decide whether it
must be eta-expanded or not.

@gebner @kha What do you think?

c35108cf0d fix(library/tactic): fixes #1369 
- `eval_expr` instantiate assigned metavariables occuring in the input
  expression.
- Rename pp.instantiate_goal_mvars to pp.instantiate_mvars
- `format_expr` also instantiates assigned metavariables before pretty printing
  when pp.instantiate_mvars is set to true.
