88de81077c feat(library/compiler/specialize): do not specialize instances unless they are marked with [specialize] 
@kha: I changed the specialization candidate selection procedure.
Now, instances are not considered for specializations unless we mark
them with `[specialize]`. The idea is that an instance application is
morally just creating the "dictionary" for invoking a polymorphic
function.

4cfe44bed0 feat(library/compiler/specialize): add nospecialize attribute 
@kha I had to add this attribute because the specializer was generated
many specialization candidates for functions that take `[has_tokens ...]`
as an argument. Moreover, these candidates had a lot of
dependencies. I am trying to workaround this issue by marking the
instances with the new attribute `[nospecialize]`.
I did not mark instances created by `[derive]`. It is quite tedious to
do it.

BTW, when I was investigating the problem I stumbled at `node.view`.
Its type is:
```
node.view :
  Π {α : Type} {m : Type → Type} [_inst_1 : monad m] [_inst_2 : monad_except (parsec.message syntax) m]
  [_inst_3 : monad_parsec syntax m] [_inst_4 : alternative m] (k : syntax_node_kind) (rs : list (m syntax))
  [i : @has_view syntax_node_kind k α], @has_view (m syntax) (@node m _inst_1 _inst_2 _inst_3 _inst_4 k rs) α
```
This looks wrong: the view depends on `[monad_parsec syntax m]`

We should also make sure definitions do not have unnecessary type
class instances. Otherwise, we will put additional stress on the code
specializer. One option is to change the frontend and filter unused
instances.
