bd03619b5c refactor(library/data/list/basic): test 'rec_inst_simp' blast strategy 
recursor + instantiate [simp] lemmas + congruence closure

b35abcc6a8 refactor(library): rename strategy "msimp" ==> "inst_simp" 
"inst_simp" means "instantiate simplification lemmas"
The idea is to make it clear that this strategy is *not* a simplifier.

f177082c3b refactor(*): normalize metaclass names 
@avigad and @fpvandoorn, I changed the metaclasses names. They
were not uniform:
- The plural was used in some cases (e.g., [coercions]).
- In other cases a cryptic name was used (e.g., [brs]).

Now, I tried to use the attribute name as the metaclass name whenever
possible. For example, we write

   definition foo [coercion] ...
   definition bla [forward] ...

and

  open [coercion] nat
  open [forward] nat

It is easier to remember and is uniform.

2185ee7e95 feat(library/tactic): make let tactic transparent, introduce new opaque note tactic 
The new let tactic is semantically equivalent to let terms, while `note`
preserves its old opaque behavior.

9bedbbb739 refactor(library,hott): remove coercions between algebraic structures
