2bc13f6bfd feat(library/tactic/exact): enforce goal type during elaboration when executing 'exact' tactic 
Remark: this was the behavior of the 'sexact' tactic.

This commit also adds the 'rexact' (relaxed exact) tactic which does not
enforce the goal type.

754276a660 feat(frontends/lean): round parenthesis for [tactic1 | tactic2] 
This commit also replaces the notation for divides
     `(` a `|` b `)`
with
      a `∣` b

The character `∣` is entered by typing \|

8295ef4e57 fix(library/tactic/class_instance_synth): constraint execution order at type class resolution 
We could not fix this problem before because we did not have the
[quasireducible] annotation.

Without this annotation, the fixed TC would loop in some HoTT files.
